Replacing your Central Heating Boiler

Boiler efficiencies are rated on an A-G scale. With a G-rated boiler, when you buy £100 of fuel, you may get as little as £60 - £65 worth of heat, and the rest of the fuel is wasted through the flue.

A-rated boilers will give you between £90 and £95 worth of heat for £100 spent , so there is less fuel wasted. Switching from a G-rated to an A-rated boiler can reduce your heating bills by up to 35%.

If your boiler is relatively old (over 10 years), we recommend that you replace it even though it still works.

Alternatively you could use a wood stove to provide a large part of your heating and keep your older boiler for back up.

Funding a New Boiler

Funding for a new boiler could come through the Green Deal or if you are on benefits through ECO, NEST and PZIL (if old boiler D rated or worse or new boiler wood fired).  ECO can also fund boiler repairs if needed.

The   Renewable Heat Incentive (RHI) is a government subsidy for installation   of renewable heat producing technologies, including central heating boilers   fuelled by wood.  Final details of this   scheme for homes are due in the summer of 2013.  Tariff payment levels (not yet confirmed but around 7.6p/kWh) should begin from October 2013.  This could be worth £2,000 per year   but installation costs will be considerably higher for eligible boilers than   for conventional gas, lpg or oil types.

Before the RHI begins up to 25,000   early adopters could also qualify for an ‘RHI Premium Payment’ of £950.

Renewable Heat Incentive payments may depend on carrying out other 'Green Deal fundable' measures to the property.

Boiler Options

There are several fuel and carbon saving options which you could consider:

Wood Log Stove with built-in boiler

  • Cost from £1,500 plus fitting, total installed cost budget at least £2,500.
  • Requires manual re-fuelling and periodic ash removal. Unlikely to be controllable via time and thermostatic controls.
  • Unless solar hot water present, immersion water heating likely to be needed in summer.
  • Unlikely to qualify for Renewable Heat Incentive (RHI) payments.

 

Hopper Fed Wood Pellet Stove with built-in boiler

  • Cost from £2,000 plus fitting. For total installed cost budget at least £3,000.
  • Requires manual re-fuelling and periodic ash removal. Time and thermostatic controls normally available as an option.
  • Unless solar hot water present, immersion water heating likely to be needed in summer.
  • Bulk delivery of pellets gives significantly better prices, but requires delivery by truck.
  • May not qualify for RHI payments, clarification on this is awaited.

 

Gasifying log boiler    

  • For total installed cost budget at least £5,000.
  • Required manual re-fuelling every 24-48 hours, and periodic ash removal. Heat stored in accumulator tanks.
  • Time and thermostatic control of heating are normally fitted as standard.
  • Expected to qualify for RHI payments

 

Autofeed Wood Pellet Boiler 

  • For total installed cost budget at least £8,000.
  • Three main re-fuelling options – manual, auto feed from adjacent pellet store or vacuum suction system allowing pellet store to be distant from boiler. Time and thermostatic controls normally fitted as standard. Ash removal required every few months.
  • Bulk delivery of pellets gives significantly better prices, but requires delivery by truck.
  • Requires pellets to be stored indoors and kept very dry. Annual pellet supply will fill at least 6.5 cubic metres. (approx size of small garden shed)
  • Expected to qualify for RHI payments.

Wood Pellet Boiler

Wood Chip boiler

  • For total installed cost budget at least £15,000 including fuel store.
  • Two main re-fuelling options – auto feed from adjacent chip store. Time and thermostatic controls normally fitted as standard. Ash removal required every few months.
  • Requires truck access to your property for chip delivery (essential).
  • Requires chips to be stored indoors and kept very dry. Annual chip supply will fill at least 23 cubic metres (approx size of 3 small garden sheds).
  • Expected to qualify for RHI payments.

Financial paybacks on these systems will vary according to current use, installation costs and the RHI payments. 

Please Note

Installers of solid fuel appliances must be approved by HETAS (see www.hetas.co.uk) or an equivalent ‘competent persons’ scheme.

Also, in order to qualify for RHI payments it is essential that your appliance and your installer are both certified with the MCS. See www.microgenerationcertificationscheme.org.

When fitting any new central heating system, make sure that it heats as many of the rooms as possible, since individual room heaters tend to be much less efficient than boilers.  Ensure that a foam insulated tank, thermostatic radiator valves and radiator panels are fitted (if they are not already).  Also consider whether you would like solar hot water in the future.
