A heat pump can extract energy from renewable sources such as ground, water and air.
You have already been using a heat pump for decades without realising it.
Your refrigerator using the same basic heat pump technology to remove the heat from the food inside the ‘box’, ejecting it to the outside and keeping the food cold.
A heat pump reverses this process and extracts heat energy from the outside air, ground or water and moves that heat into your home (hence ground source or air source heat pumps).
Using the same ‘vapour compression cycle’ as your fridge to produce heat, the heat pump can take a few degrees of outside heat and upgrade it to provide all the heating and hot water you need.
An air source heat pump, such as the market-leading Mitsubishi Ecodan range, is essentially a ‘box’ that sits outside your home and uses a fan to draw air through the refrigerant piping, where the heat energy is harvested and upgraded.
The heat pump runs on electricity and will ‘convert’ each kilowatt of electrical energy into 2, 3, 4 or more kilowatts of heat energy. This ‘free’ energy taken from the air is replaced each day by the sun and is therefore renewable energy.
A Ground Source Heat Pump works in the same way but recovers it “free” latent heat from the ground instead.
There are a number of factors affecting the cost of installation such as the age and size of your property, the levels of insulation and thermal efficiency, the number of rooms and radiators, etc, so it is difficult to give even an average idea of cost.
We recommend sending us a floor plan and most recent EPC so we can give you an idea.
This depends on what system of heating you currently use but even with a gas boiler, you are likely to make significant savings. For oil, LPG or direct electric heating the savings could be even greater.
Clicking on the link on the right will allow you to answer a few simple questions to indicate the likely savings you could make
Again, there are a number of factors that will affect this but for a new-build and existing home, most air source heat pumps can be installed in a week.
For a refurbishment, it depends whether your radiators also need replacing, whether your water cylinder needs re-siting, where the outside box will be fitted, etc.
It will also depend on whether you are completely replacing the existing heating system or simply adding a heat pump to work alongside the current heating in a hybrid solution.
Mitsubishi has been manufactured in the UK for more than a decade now and we have invested heavily in Research & Development to make sure that it is designed specifically for UK conditions.
The system will continue working to maximum efficiency down to -10C and will carry on working to -20C or more, so you can rely on a warm and cosy home even when there is snow on the ground.
The outdoor part of the system does have a fan which draws the air across the internal components and this will make a whirring noise in operation. The amount of noise depends on the quality of the product and this is where the Ecodan range has led the market in the UK.
Ecodan has always been amongst the quietest heat pumps available and our latest model is ‘Ultra Quiet’, running at a noise level almost equivalent to the noise in a typical library.
Under Permitted Development regulations, an air source heat pump noise level must not exceed 42dB(A) 1m away from a neighbour’s nearest room.
You will also need to keep 1m from a neighbouring boundary to keep within Permitted Development (the same reason you do not need planning to erect a shed in your garden).
With Ultra Quiet Ecodan air source heat pumps can be located much closer to the your neighbour’s property and pass planning.
The latest models offer superb style, market-leading energy efficiency and sound levels and are 3 times quieter than previous models virtually eliminating planning restrictions.
Should you have a large property that requires more than one heat pump, planning will be required.
Depending on your current system you may be able to utilise your existing controls however Mitsubishi and Daikin already come with sophisticated smart controls that allow you to monitor and control your heating from anywhere. Mitsubishis MELCLoud app is part of the package and allows you to see and change settings from your sofa, your office, or the poolside.
In addition to this, you are able to see how much energy you are using, allowing you to spot trends and vary your heating to match your needs with maximum efficiency and minimum cost.
These advanced controls also mean that both we and your installers can access your system remotely to check your system is running as efficiently as possible and troubleshooting if ever necessary.
We have a selection of installations locally that you can view subject to a heat loss survey, additionally we have a number of customer testimonial videos from Mitsubishi, showing heat pumps in a variety of properties, which can be viewed here.
The efficiency of a heat pump depends on factors such as the energy source or how well insulated the building is.
Delivering a whopping 77% saving on emissions versus gas, see how ground source heating compares to the familiar boiler. Depending on Air or Ground Source there are a number of variables. One key point is that all systems require a hot water cylinder and there are no “combination” units currently available.
There are many factors that differentiate air source from ground source heat pumps – including the fact that air source units absorb heat energy from the air, and ground source units from the ground or water
Ground source heat pumps can absorb energy from sources such as soil, water or rock. A water source heat pump absorbs energy from bodies of water such as ponds, lakes or even the sea. Slinky pipes and straight pipes are forms of ground arrays used to collect heat from surface soil. A borehole is a type of ground array that uses vertical pipes bored into the ground, this saves space required for a ground array.
