Government Scheme For Boilers -Gov Uk Grants [2022]

What is the New Government Scheme For Boilers  ?

 

The Boiler Upgrade Scheme (BUS)  is a new boiler grant scheme which will be live from  April 1 2022 to aid in the decarbonisation of buildings in preparation for the Uk 2050 target for zero carbon emmissions.

This scheme is aimed at encouraging householders to switch from mains gas boilers  to heat their homes with financial assistance of a new £5000 grant.

This £5000 grant should make it as cheap for people who need to change their boiler to move to a low carbon heat source instead such as heat pumps which at present cost anything from £8000 onwards.

The grant should accelerate the installation of air source heat pumps, ground source heat pumps and, biomass boilers in areas that are off the gas grid..

The BUS will be open to all properties located in England and Wales.

We anticipate that there will be strong take up as heat pumps are very efficient and will reduce heating bills by up to £300 per year.

How Much Do Heat Pumps Cost ?

 

Heat pumps aren’t cheap unfortunately.

A  typical air source heat pump installation will cost you around £6000 – £8000,

A ground source heat pump installation can cost between  £10,000 – £18,000 depending on the size and amount of heat required.

We are hoping that the scheme will cover 70% of  the cost of upgrading to a heat pump and that the maximum people will have to contribute is around £2500.

Nothing has been finalised at the time of writing  (April 1)

 

Will The New Clean Heat Grant Cover All The Cost ?

No.

With the end of the Renewable Heat Payment, the new clean heat grant will only pay £5000 towards the cost of a heat pump.

What Is A Heat Pump?

 

Heat pumps are  a relatively new source of home heating and are becoming more popular due to their low running costs and zero carbon emissions.

A heat pump is very similar to a domestic refrigerator and looks very much like an air conditioning system that you see on your holidays in your hotel rooms.

It usually is a silver  rectangle box that is situated outside on your wall that has a fan fitted.

 

How Do Heat Pumps Work?

They work by taking the available heat from the ground or air surrounding a property and increases it to a more useful temperature for use in the home.

It achieves this by taking the same principle that allows a fridge to cool your groceries and by utilizing it in reverse.

This is a constantly renewable source of heat which is used to create warm air , and hot water .

Indeed its use does make gas boilers redundant.

Heat Pump Operation

 

  • The source of heat,  (can be outside air or a water mix which is contained within ground collectors)  is either blown or pumped over the heat exchange surface of the outside part of the heat pump.
  • This heat is warm enough to cause the special refrigerant liquid to evaporate and turn into a gas.
 
 
 
  • This gas is then compressed which increases the pressure and temperature of the gas .
 
 
  • The gas (now heated) is passed over the internal heat exchange surface.
  • This heat can then be either blown around a property or be transferred into a home’s central heating or hot water system.
  • The gas falls in temperature as the heat is transferred into the home and it subsequently returns to a liquid state.
 
  • The refrigerant returns to the outside heat exchange surface and the process repeats itself until sufficient heat is passed into the home.

 

 

 

Ground and air source heat pump running cost

 

Here’s an idea of what a ground source or air source heat pump’s running costs could look like per kilowatt hour of thermal energy.

With the cost of heating rising, we advise you add another 25% to the prices below

We have compared heat pumps compare vs. boilers and other forms of central heating, along with their respective boiler efficiencies.

Heat Generator
Heat generator efficiency
Type of fuel
Cost of fuel (p/kWh)
Running cost (p/kWhth)
Air source heat pump SCoP 3.9 Electricity 16.36 4.19
Ground source heat pump SCoP 4.1 Electricity 16.36 3.99
Electric storage heater 98% Electricity 16.36 16.69
Gas boiler 98% Gas 4.17 4.26
LPG boiler 95% LPG 7.19 7.57
Oil boiler 95% Oil 4.81 5.06

You will see that heat pumps compare more favourably than other types of heating at the moment but the government will make electric more cheaper in the future to encourage take up of heat pumps

 Insulation Is a Must For Heat Pumps

 

Air source heat pumps work at low temperatures so, so if a home it is not sufficiently insulated, this will need to be improved to get the maximum benefit of having a heat pump  installed.

Heat loss through the walls, roof and floors all must be minimised to enable efficient operation.

We recommend you Look at 3 areas before fitting a heat pump

 

  1. Loft insulation
  2. Wall insulation
  3. Double glazing

 

Loft insulation

Loft insulation is an easy measure for most households and you can DIY for £200 in materials or have professionally done for around £600

270mm of wool insulation needs to be laid within the loft to get the required u-value of 0.16W/m2k for maximum savings.

 

Wall insulation

 


Properties built after 1935 usually have cavity walls and  are relatively simple to insulate.

Cavity wall insulation involves the walls being drilled into and the insulation is injected within. This job should cost approximately £10 per m2 of wall.

Solid wall properties  can either be clad with insulation on the outside or have insulation attached inside.

Solid wall insulation procedures are more costly and can cost from £7500

New homes built since the late 1990s should have already have more than adequate insulation but worth a check.

Current building regulations mean that homes built today are incredibly well insulated, allowing a heat pump to be the ideal heat source for these properties and helping the running costs to be significantly cheaper.

 

Double glazing

Installing double glazed windows is another measure which can help a home become ideally suited for a heat pump.

Windows are an outlet for heat to escape a home so upgrading from single glazed to double glazed will greatly reduce a property’s heat loss.

According to the Energy Saving Trust, by installing double glazing, a single-glazed detached home could save over £100 on their energy bills every year.

 

The Benefits Of Double glazing

  • Double glazing will increase the amount of heat that can be kept inside a home.
  •  Your property will  feel warmer and not use as much heating .
  • You will reduce  both the carbon footprint of a home and  energy bills too.
  • It can be an effective barrier against noise, reducing the amount of sound transmitted into the home,
  •  Serves as deterrent against intruders, helping to heighten the security of a property.
