Heat Pumps use the free available environmental warmth to guarantee the heat supply of a property. This is one of the most economical, effective and at the same time environmentally friendly ways to ensure hot water and heating comfort. There are two kinds of Heat Pumps - Air Source Heat Pumps and Ground Source Heat Pumps.
We use and recommend the Vaillant Heat Pump product range which includes the aroCOLLECT, aroTHERM, geoTHERM and flexoTHERM units.
We are MCS Accredited Installers in Hertfordshire, which allows clients to benefit from the Renewable Heat Incentive. You can read more information on RHI on the ‘Get Paid for Staying Warm” section below.
AIR SOURCE HEAT PUMPS
Air Source Heat Pumps are often used when it is not possible to drill in a ground probe or install a surface ground loop on a property for a Ground Source Heat Pump. Not only is this cost efficient, but the only space requirement is an outside location making them ideal for homes with limited outside space.
Air Source Heat pumps work by converting the energy of the outside air into heat, creating a comfortable temperature inside the house as well as supplying energy to the hot water system. As with all heat pumps, air source models are most efficient when supplying low temperature systems such as underfloor heating.
Air Source heat pumps should cover the heating requirements of a well-insulated property in all but extreme weather conditions. When used in combination with an immersion heater both heating and hot water needs should be met, the immersion heating boosting water temperatures when necessary.
GROUND SOURCE HEAT PUMPS
Ground Source Heat Pumps work by using heat stored in the ground from the sun's solar radiation to supply all of the energy required for a home's heating and hot water system. The top 15 metres of the Earth's surface maintains a relatively constant temperature of approximately 12 degrees Centigrade. This energy can be used to heat buildings indirectly.
Pipe is buried in the ground, either in a borehole or a horizontal trench. The pipe is usually a closed circuit and is filled with a mixture of water and antifreeze, which is pumped around the pipe, absorbing heat from the ground. In winter the ground is warmer than the air and buildings above.
The anti-freeze mixture absorbs heat from the ground, which is then concentrated and transferred to the buildings. This heat can be used to heat domestic water and a low temperature heating system such as under floor heating.
DOMESTIC RHI SCHEME
GET PAID FOR STAYING WARM
What is it? The Domestic Renewable Heat Incentive (Domestic RHI) is a government financial incentive to promote the use of renewable heat.
The Domestic RHI Key to joining is that the renewable heating system heats only a single property which is capable of getting a domestic Energy Performance Certificate (EPC). The EPC is the proof we need that your property is assessed as a domestic ‘dwelling’. Without one, you won’t be able to apply and can’t join the scheme. An EPC gives information about a property’s energy use, plus recommendations on how to reduce energy and save money. It’s required every time you buy, sell or rent a property.
Who's it for? The scheme's open to anyone who can meet the joining requirements. It’s for households both off and on the gas grid. People off mains gas have the most potential to save on fuel bills and reduce carbon emissions.
As we are accredited MCS installers our clients can benefit form the Renewable Heat Incentive.
What are tariffs? These set the rate for your Domestic Renewable Heat Incentive (RHI) payments. People who join the scheme and stick to its rules, receive quarterly payments over seven years. The rates are set by the Department of Energy and Climate Change (DECC) and we publish current and historical tables here.
