Ground source heat pumps deliver typically £450 savings in energy costs per property versus direct electric.

Get paid to save

Ideal for individual or groups of existing or new-build holiday accommodation, Kensa’s ground (or water) source heat pump solution provides each property with a complete renewable heating and hot water system, able to provide 100% of the property’s heating and hot water needs all year round at a fraction of the cost of electric or LPG heating – great for off-gas grid sites.

As further incentive, holiday accommodation with ground source heat pumps gets 20 years of non domestic RHI payments – get paid to heat your properties!

Efficient heating

A heat pump produces up to three times more energy than it consumes. So for every 1kWh of energy your heat pump uses to power itself, you will get typically 3kWh of energy to heat your property.

Translate this into heating costs, and your savings will soon start to stack up – especially compared with LPG and electric heating.

Add in the additional income you are guaranteed through the Renewable Heat Incentive (RHI), and you can expect a payback in around 8-10 years, with a healthy profit for the balance of the 20 year RHI scheme.

Compare your heating options

By using a high proportion of “free” renewable energy from your sites natural resources, ground source heat pumps can demonstrate savings of more than 65% compared with direct electric heating and over 50% compared with LPG.

Better still, the RHI income at 9.1p/kWh is more than double the cost of producing a unit of heat from the ground source heat pump, meaning it is cost effective to maintain a level of background warmth in the property between occupancy periods, preventing damp and providing a warm welcome to your next set of guests.

Clean & green

With more and more visitors being eco-conscious, it’s good to know that ground source heat pumps are a much cleaner, greener energy solution than LPG or electric.

Lowering your CO2 footprint and eliminating other harmful emissions, ground source heat pumps help to create a healthier environment for your customers and boost your accommodation’s eco-credentials

Peace of mind

Guaranteed income

In addition to reduced energy bills and a guaranteed non domestic RHI income for 20 years, holiday accommodation owners will also appreciate low service, minimal maintenance and low whole life ownership costs of ground source heat pump systems.


Protected from the outdoor elements by being housed inside the property itself, Kensa’s unique Shoebox heat pump or the new Evo heat pump can be expected to provide a service life of at least 20 years, while once installed, the ground array will provide a renewable energy source for four to five times that, servicing replacement heat pumps long into the future.


No servicing

Ground source heat pumps make use of standard refrigeration technology, and just like a domestic refrigerator, are fully factory sealed meaning they have no regular servicing or ongoing preventative maintenance requirements.


Unlike an LPG boiler, there is no fuel combustion, meaning heat pumps do not require an annual safety inspection and there is no risk of carbon monoxide poisoning.

No bulk fuel

There is no longer any need for bulk fuel purchases or fuel storage areas – the electricity needed to run the heat pumps is simply provided by each property’s electricity supply, while the rest comes free from your sites natural resources. As such, lifetime ownership costs are far lower than any other technology.

How the savings stack up

Here’s how the savings and benefits can stack up for holiday accommodation, based on a typical 70m2 property:

Cost per unit of heat (p/kWh) 1£0.06£0.11£0.037
Typical annual running cost 3£368£674£225
RHI payment per unit of heat (p/kWh) 2--£0.088
Annual RHI Payment 3--£540
Annual CO2 emissions (kgCO2)212336021220
Annual fuel cost saved by using a GSHP instead£195£450
Total annual benefit by using a GSHP instead£735£990
Total benefit over 20 years by using a GSHP instead4£17000£24000
  1.  LPG 32p/l, 80% average boiler efficiency. Electricity 11p/kWh, 300% GSHP average efficiency.
  2. Non Domestic RHI, based on metered heat consumption.
  3. Presumes 80% occupancy on average across the year, weighted by month. Assumes lodges are available for rent all year round, background heating is used to maintain a base temperature when unoccupied.
  4. RPI index linked, presuming 2% inflation for both RHI increases and fuel price inflation.

Living where we do, surrounded by rolling Welsh hills, we are very conscious that our luxury holiday accommodation should strive towards being eco-friendly. To do this we decided we wanted a heating system that paired technological innovation with natural resources. It is also very important for our guests to be comfortable during their stay with access to a constant supply of heating and hot water.

The Non-Domestic RHI

The purpose of the Non-Domestic Renewable Heat Incentive (RHI) is to compensate for the cost of installing ground source heat pumps in commercial applications, providing a long term rate of return and fast payback for business owners, developers and social housing providers.
