Do You Have A Project We Can Help With?

Contact Us

We encourage you to engage our services as early as you can.

The majority of our chargeable services are fully refundable when you place an order with Eco Installer and one of our Trusted Partners. We do this because we know how much value we can bring to a design at the early stages.   

Adjusting the size of a room to accommodate equipment at a late stage, or altering construction specifications to suit certain technologies can be costly and can be avoided if the design is right at the beginning.

Renewable Heating and Plumbing Services

For customers within 1-hour of our office in Ely, Cambridgeshire, we can design, install, commission and support a mix of systems from traditional to renewable energy using our own employed workforce. And outside this area where we have a Trusted Partner in place. More recently, we have added expertise in mechanical ventilation heat recovery, air conditioning and comfort cooling, wet and dry stove installations, infrared, smart controls and electrics.

Government Funding for Renewable Installations

For customers who wish to access Government funding, Renewable Designs is registered with the Microgeneration Certification Scheme (MCS) for Solar PV, Biomass and Heat pumps installations, so we can issue the certificates that are required to apply for funding.

Heating with wood (solid fuel)

Today standalone stove installations are incredibly popular and with good reason. Heating with wood (solid fuel) is an effective way of heating a property, done correctly it is sustainable for the environment and provides a focal point in a room.

Solid Fuel Heating

For some projects solid fuel could be the best option. This could be due to power concerns/restrictions (risk of power cuts, not enough power to run a heat pump, or no mains power to the site). It could be a lifestyle choice, or one made for financial reasons (a cheap or free supply of virgin wood).

We can help with advice and design of central heating systems running on solid fuel alone, or in combination with an automatic boiler of some kind (heat pump, electric, oil or gas boiler typically).

Please note that our design charges are not usually refundable for solid fuel where the installation cannot be undertaken by our own personnel. Please check before you engage with us, to make sure that we have a suitably qualified partner to cover your area.

Solar Photovoltaics (Solar PV) For Electricity

Almost every project will benefit from the installation of Solar PV, whilst they are not everybody’s ‘cup of tea’ with the latest flat roof, in-roof and ground mounted systems, we believe that there is a system to meet any budget and the approval of any a discerning eye.

How Solar Energy Can Be Used

The energy generated can be used, either to run everyday appliances, to charge an electric vehicle or to run a heat pump that is supplying the property with heating and hot water.

Government Funding For The Installation Of Solar Panels

It’s a no-brainer really. Why not get paid to generate the electricity you are going to use anyway? Many people believe that there is no more funding for solar panels but this isn’t the case. Whilst the tariff has been greatly reduced from the early heady days, there is still a healthy return and with most new-build systems benefiting from reduced or zero rate VAT, a payback of somewhere between 10 and 12 years is possible.


What is a Mechanical Ventilation with Heat Recovery (MVHR) system?

In simple terms an MVHR system reuses the energy in the air that would have otherwise been wasted as part of the process of getting the moisture within the air, that is usually associated with bathing and cooking out of the building.

What properties are suitable for a Mechanical Ventilation with Heat Recovery system?

MVHR is not suitable for every project, for instance the homeowners might prefer to sleep with windows open (all year round). The type of joists and or layout of them might not be suitable, or there simply might not be sufficient space within the building to house all the equipment and ducting.

However, if MVHR is suitable for the project, then it can have a massive benefit in terms of looking after the health of the building’s fabric and occupants. It can also significantly reduce the amount of energy required to heat a building (this is dependent on the amount of energy the system is able to reuse).

Mechanical Ventilation with Heat Recovery System Design, Installation and Support

We can provide design, installation and ongoing support for the Systemair range of domestic and commercial MVHR systems, locally through our own directly employed workforce, or through their/our trusted partner network. If you are not local to us, please check first to make sure that we have cover for your area before you engage our services.

Solar Battery Advice

We are of the opinion that you are better waiting for current battery storage offering to improve, both in terms of functionality and cost.

The government has announced plans for a smart grid, which will see different rates for electricity depending on the time of day that you purchase it.

This is all will be great news if you have an intelligent system to control when your home appliances run, you charge your electric vehicle, heat your home or domestic hot water, or even charge your solar batteries. However that technology is either too expensive, not reliable or not yet available.

For us the intelligence needs to go further, we believe that smart grid ready batteries should be able to sell electricity back to the grid at the highest rate and decide when they should charge at the lower electric rate based upon how much solar generation they are likely to still get that day, less any likely consumption. It’s complicated and because of this we think the huge expense and limited lifetime of solar batteries make them a limited decision in the majority of instances for now.

Finally, any form of Solar storage are heat batteries. We have successfully installed 2 x Sunamp PVs for a customer just outside Norwich and he is delighted with them. Sunamp can either storage energy for domestic hot water generation or heating and hot water generation.

Should you consider any other forms of heat or energy recovery?

In a simple answer – Yes.

Shower Heat Recovery Units (SHRUs) or Waste Heat Recovery Units as they are also known are very efficient at reducing hot water consumption in the shower if you have a thermostatic mixer shower. They have little to no moving parts, they require very little maintenance and are only in use when you are using the shower so no energy is wasted.

Some of our customers have to recycle grey water as part of their planning conditions. Whilst these systems can be very clever, we have had issues with some of the after-sales support. So our message is buyer beware.

Comfort Cooling with Climate Control

If you planning to work from home, or suffer from extreme temperature changes, then you might wish to consider some form for comfort cooling or climate control in your new home. This can be achieved either through the installation of an air conditioning system, an air to water heat pump that can be reversed during summer month to provide cooling through fan assisted radiators, or a through comfort cooling connection with your Mechanical Ventilation with Heat Recovery system (MVHR). It is also possibly to get a comfort cooling connection for an air conditioning system and this can sometimes be the easiest option because it simplifies the control.

Comfort cooling will only lower the incoming supply air by 1 or 2 degrees C, so if you require a more precise form of climate control, then you should consider either a standalone air conditioning system, or a combination of standalone air conditioning and comfort cooling through the MVHR system.

First Floor Heating Options

With the increased levels of insulation and reduced air changes in our new build property, do we need heating on the first or second floor? This is one of the most common questions that we get asked and to answer it is important to consider various factors.

In theory, if the property follows the traditional model of warmer rooms on the ground floor (lounge, dining room, study etc.) then you probably won’t need heating on the first floor, other than bathrooms or ensuites, although this is down to personal preference.

If you are planning to sell the property then you will need to consider whether a lack of heating upstairs could limit the appeal of your home as potential buyers may be unfamiliar with how well new build homes hold on to their heat. This should become less of a problem in future as Estate Agents and buyers become more aware.  

Customers Specific Heating Solutions

Some of our customers prefer to install underfloor heating on all floors, even though it won’t be in use much. This tends to be the most expensive option. Other customers go with radiators, or a first fix for radiators, where pipework is installed and capped off in the floor or wall ready for future use. Radiators are the less expensive option if upfront costs are a concern with the first fix being the least expensive.

Heating To Meet Your Lifestyle Choices

Other factors to consider are lifestyle choices, is the homeowner likely to open the windows on a sunny winter’s day? If this is the case, then it’s possible that the building will require heating on both floors.

If your building is going to have weather compensated heating, then the surface temperature of your underfloor heating or radiators might not feel warm to the touch, even though the system is maintaining the required air temperature. This might not be an issue and for many of our customers it is not, however some like to add a layer of electric underfloor heating mat to their bathrooms and ensuites, so that they can have a warm feeling under foot when they step out of the shower.

If you are thinking of installing electric underfloor heating then you should consider Solar PV at your new property as you could probably provide most of the electricity you need from this.

BS EN 18311 Room By Room Heat Loss Calculation

The best way to evaluate which heating technology is suitable for a project is with a room by room heat loss calculation.   

If you don’t yet have your final construction u-values, we can use what you have and complete the rest using standards needed to meet latest building regulations.

Mechanical Ventilation Heat Recovery, Peak Power Requirements 

Mechanical Ventilation Heat Recovery (MVHR) can have a huge impact on the peak power requirements and it is important to factor this in when considering the size of your heat generator and its modulation. We will always ask whether you are considering MVHR for your project and will produce a summary with and without it if this features in your plans.

Once you know your design heat losses per square meter (heat loss/m2) you can investigate what impact an improvement in construction u-values, and or reduced air changes can make. Emitters (radiators, underfloor heating, fan assisted radiators etc.) must be sized to meet and or exceed the particular heat losses of each room. In some instances the same sized emitter can provide different outputs, according to the temperature flowing from the heat generator (boiler, heat pump etc.). With heat pumps in particular if you increase the flow temperature it will increase the running costs at the same time reducing the income from the Renewable Heat Incentive. Therefore it is important to gain as much insight into the project as early as possible, so that all options can be considered before the design, time or budget becomes restrictive.   

Perhaps you have a planning condition that needs to be met with a percentage of Renewable Energy?

It’s not uncommon for a modern planning condition to state that you must “demonstrate that at least 10% of the developments total predicted energy requirements will be from on-site renewable sources”.

We are best placed to help you find the most economical way of satisfying a criteria like this.

We know that you will want to maintain the look of your development and we will consider this with any recommendations that we make.

The earlier that you can engage us, the easier it is for us to come up with a simple solution, however don’t worry if you are part way through the build or even at the point of trying to get the building signed off by building control, as we can help at any stage.
