Maximise heating efficiency

Solar panel systems

Green Energy Services can fit solar panels for production of hot water in both direct and diffused sunlight, converting the energy into heat for free hot water.

A correctly configured solar panel system should produce around 50-70% of your home hot water requirements.

We fit solar panels to a design that complements your existing heating systems that use a cylinder to store hot water, and these are a perfect partner for modern condensing gas and oil boilers.

Ground source heat pumps

A ground source heat pump is an electrically powered system that uses energy that is naturally stored in the earth to heat your home. They can provide low-cost and comfortable heating levels by using sustainable energy, creating no direct carbon emissions or damage to the environment.

We design these systems to be either complementary to your existing hot water system, or they can be the sole source of heating and hot water. Another option is to combine heat source pumps with solar panels, for larger properties.

By using a correctly designed and installed ground source heat pump system, you can multiply the energy used to run the pump by a factor of 4, meaning that for every kilowatt used by the pumping system, you could receive a gain of 4 kilowatts to heat your home.

Planning permission for use of these systems is now much easier to obtain, and as trained engineers we will guide you through the planning process.

Call us now to learn more about how an investment in this technology will produce payback for you and your family in years to come; as well as cutting your carbon emissions as soon as the installation is completed.

Grants may be available (see right)!

Ground heat source pumps attract potential grant status from the Low Carbon Buildings Programme. You may receive up to £1,200 or 30% of the relevant eligible costs, whichever is the lower.

By combining heat pump and solar panel investment together, then a household may receive up to £2,500 as a contribution to the installation. We can advise on the grants available, and your local authority also has information on funds available, and planning permission requirements.

Underfloor heating systems

Imagine the freedom of interior design that comes with a central heating system that has no traditional radiators!

Imagine a silent heating system that gives the same level of comfort in all areas of the room! Imagine savings up to 40% of your annual heating fuel costs, and reducing your carbon emissions at the same time!

All these important factors are possible with underfloor heating from Green Energy Services.

So how does it work?

Modern underfloor heating systems are generally either warm water systems or electric systems. At this time, we only supply and install water systems from Rehau, a leading building products company that leads this field of expertise.

Systems can be poured into a masonry mix (called a poured floor system or a wet system) or fastened directly to the sub floor (called a sub floor system or dry system). In this way it is possible to install underfloor heating in and existing building, and on the first floor that is not normally of concrete construction.

In a hot-water system, warm water is circulated through pipes or tubes that are laid into the floor (usually a solid-screeded floor, although joist-based systems also work well). Various types of pipe are used including PEX, multi-layer and polybutylene (PB): copper pipes are not normally used.

In Europe, including the United Kingdom, 15 mm or 16 mm pipe is commonly used, and we plan pipe layouts using Rehau systems which have a strong and established reputation.

A small in-line centrifugal pump is used for circulating the water around thermostatically controlled ‘zones’ (i.e. rooms). It will circulate water through the tubing fast enough to dislodge any air bubbles and runs silently. The pump only activates when the system anticipates a need for heat in any zone; and brings warm water to that zone by switching on the boiler or by collecting warm water from a solar panel or ground source heat pump.

Gas, oil, solid fuel, or electric-resistance hot-water boilers can be used as the source of heat for any underfloor heating system, as can a number of other technologies. Condensing boilers and ground-coupled heat pumps are particularly well-suited as the large radiating area of underfloor heating systems allows them to operate in their most efficient manner. Underfloor heating can be run at as low a temperature as 30 °C, allowing a heat pump to run at a coefficient of performance in excess of 4.0, compared to less than 3.0 with the high temperatures needed 75 °C for use with small wall-mounted radiators. The critical factor for achieving a high coefficient of performance is to reduce the "uplift" or delta-Temperature needed between the heat source and the heat sink.

Although it can be more expensive to install than radiators (it can be comparable due to the increasingly competitive market), wet underfloor heating often proves more economical in the long run, particularly in well-insulated larger properties. Energy savings of up to 40% can be achieved compared to conventional heating systems if a condensing boiler or solar thermal system is installed, but even with a standard boiler up to 15% energy savings are normal. The efficiency of condensing boilers is enhanced thanks to water returning at a lower temperature.

By employing full lengths of piping without any joints, wet underfloor heating loops are practically maintenance free. The piping is guaranteed for at least 30 years. Reliable materials are critical because repair is difficult. The central heating equipment, pumps, and controls, like others, requires periodic maintenance and replacement.
