To check an appliance meets Building Regulations and Standards for safety& efficiency, look for HETAS approval.

The product search on the HETAS website includes all HETAS Approved Appliances including stoves, biomass systems, boilers and chimney systems.

All HETAS Approved Appliances meet minimum efficiency requirements. These efficiencies are found on the HETAS website Product Search as ‘gross’. Appliances not approved by HETAS may still be suitable to use, but must be verified by Logic prior to installation.

HETAS Registered Installers & Servicing Engineers are trained, registered and insured to work on solid fuel, wood & biomass heating systems in your home.

Look out for the HETAS registrant marks

Whether you need an installer or service engineer. Call Logic on 017683 51812 to arrange an appointment

Check you installer is registered with HETAS

The law in UK and Ireland states that new solid fuel, wood burning or biomass appliance installations must meet Building Regulation standards and your Local Authority must be notified. Failing to do so means the work is not legal and you could face prosecution and a fine

Using an installer from a government approved Competent Person Scheme such as HETAS is a safe and easy way to ensure work is legal.

HETAS installers are able to:
∙ self-certify their own work
∙ supply a Building Regulations Compliance Certificate for the job


HETAS Registered installers are trained and regularly inspected to ensure they comply with the latest industry regulations and standards.

> Building Regulations state that new or replacement systems in dwellings must achieve the most energy and carbon efficient installation possible.

> If an existing heating appliance is replaced, it must be more efficient in terms of carbon emissions than its predecessor. This can be achieved through both appliance and fuel type.

> New-builds are subject to stringent energy and emission targets.

> Wood fuel is generally accepted as carbon neutral; a wood burning stove in a new-build allows more flexibility with other energy and carbon saving elements.

In Smoke Control Areas solid fuel appliances must be either:
∙ A DEFRA Exempt Appliance using fuel specified in the appliance instructions
or
∙ Any appliance burning an Authorised Smokeless Fuel (e.g.anthracite) which is designed for use with that specific fuel

Exempt Appliances - DEFRA Exempt appliances are tested to show they meet standards for emissions when burning nominated fuels.

Authorised Smokeless Fuels - A popular smokeless fuel is anthracite which is high in carbon and low in volatile matter. Firewood is not an Authorised Smokeless fuel, even if seasoned correctly, so must be burnt in an Exempt Appliance. EACH appliance has suitable fuels listed in it’s instructions.

The HETAS online appliance search highlights DEFRA Exempted appliances labelled with the icon to the left. These have been tested to ensure they meet emission standards when burning non-authorised fuels like wood. Try HETAS fuel search at: www.hetas.co.uk/consumer/fuel-schemes/

The answer to this is often yes. Chimneys are lined for various safety-related reasons - newer chimneys may not require relining, but systems pre-dating 1965 often require a modern lining solution if:

  • The flue has lost integrity, causing smoke leaks
  • Condensates or tar deposits are seeping through the chimney, causing staining to the building
  • Lining with insulation needs to be added to improve appliance& flue operation, especially when the chimney is exposed to the outdoors on any of its walls.
  • Defective flue systems maybe eroded & coarse, causing resistance to flow of gases & resulting in poor up draught
  • Larger chimneys/flues may affect appliance performance and require reduction in size. Some manufacturers specify smaller flues to operate more efficiently

A chimney needs to remove all combustion products safely to the outside of the building. It works because the hot gases rise to escape to the cooler air outside. Factors such as running the appliance at a very slow rate or cold air leaking into the flue cool the gases and may affect chimney performance.

Lining Systems can replace flues in existing chimneys. Insulation may need to be added or integrated to improve draught efficiency - particularly for external situations.

It is recommended that you use a HETAS Registered Installer to carry out any lining work.

Although Building Regulations do not require all existing chimneys to be lined, the installer must be satisfied a chimney is safe for use and may need to use a liner to achieve this.

*** Any work on a chimney, including its liner in conjunction with installing a heating appliance must be undertaken by a Competent Person or approved by your local Building Control by law.

Any fireplace alteration carried out to make it suitable for use with another fuel e.g. gas to solid fuel is subject to Building Regulations.

> At least twice a year if burning wood or bituminous house coal
> At least once a year if burning smokeless fuels.

The best times to get a chimney swept are just before the heating season and after an extended period of shut-down.

If sweeping twice a year, the second time should be after the peak heating season.

Before installing a liner, get your chimney swept by a professional chimney sweep to remove any soot and tar deposits.

If you already have a liner installed, a competent sweep can inspect for faults. Faults with a chimney and its liner can lead to various problems with the operation of a solid fuel appliance, and more importantly, put the safety of household occupants at risk.
