SCWS Boiler Technology (for sealed heating systems)

Our Safety Cold Water System (SCWS) has been developed to enable select woodburning boiler stoves to be safely connected to a sealed heating system. We have developed a sealed heating system boiler due to the increasing trend in Europe and the UK for sealed heating systems. A sealed heating system boiler facilitates the integration of solid fuel boilers into the house existing heating system without the need for any means of incorporating a vented boiler into an unvented system and the associated pipe work and controls


Traditionally solid fuel burners would be installed onto “open vented” heating systems (this means in the event of overheating, water can overflow into your header tank/feed and expansion tank). With a sealed system you have no open end for the water to overflow so you need an alternative system for coping with overheating. SCWS enabled appliances contain a coil of pipe within the boiler. One end of the coil gets connected to the mains cold feed and the other to a suitable drain. In the event of overheating, mains cold water is allowed to pass through the coil thereby wicking away heat from the boiler and protecting it. The SCWS system requires no electricity and will therefore operate in power cut situations.

The SCWS requires that you have mains cold supply to the property. Properties using water butts or wells are not suitable.  


In order for the SCWS product to carry full warranty and support from Broseley Fires, the installation MUST be designed, installed and commissioned by a competent person with one of the following minimum technical competence sets

Set One Installer has HETAS Wet H004 and G3 Unvented certificates.
Set Two Installer has HETAS Biomass H005 certificate. 
Set Three Installer has MCS Biomass certificate.

For installations onto open vented heating systems the G3 certificate is not required. If your installation involves other heat sources (solar, gas, electric and heat pumps) then additional competences will be required.

Roles & Responsibilities

It is the responsibility of the retailer to ensure that prospective customer is made fully aware of the installation requirements as well as the responsibilities mentioned below:  

  • It is the responsibility of the end customer to make sure that their chosen installer meets the minimum competence requirements.
  •  It is the installer’s responsibility to ensure that the installation is carried out in accordance with the Broseley Fires installation instructions as well as current building regulations. Installations not complying with Broseley Fires installation instructions will not be supported in any way.


Please note Broseley Fires do not design heating systems, however we do offer guidance in the product installation instructions on the minimum requirements of the system. The installer is responsible for any and all aspects of the installation. A site survey will be necessary to assess the heat requirement of the property and the suitability of the desired appliance for the clients needs. The heating system will need to be designed by the installer and detailed plans produced.

It may be necessary for other tradesman and sub-contractors to become involved in the installation (such as electricians) these individuals should be working to the installers plans and specifications. The installer is ultimately responsible for the final installation (hence they will need to approve all sub-contracted work). Finally the installer MUST provide a commissioning certificate to the client for the final completed installation.

Smoke Exempt Appliances

What is a Smoke Exempt appliance?

When burning in a smoke control zone you either have to burn approved smokeless coal or have a smoke exempt appliance for burning wood. Smoke exempt appliances simply burn efficiently enough to meet the strict government standards for burning in a smoke control zone, appliances are tested for this standard by DEFRA.

What is DEFRA?

DEFRA is the government body responsible for testing and approving solid fuelled heating appliances for use in smoke control zones.

History of smoke control zones

The Clean Air Acts of 1956 and 1968 were introduced to deal with the smogs of the 1950s and 1960s which were caused by the widespread burning of coal for domestic heating and by industry. These smogs were blamed for the premature deaths of hundreds of people in the UK. The Acts gave local authorities powers to control emissions of dark smoke, grit, dust and fumes from industrial premises and furnaces and to declare "smoke control areas" in which emissions of smoke from domestic properties are banned. Since then, smoke control areas have been introduced in many of our large towns and cities in the UK and in large parts of the Midlands, North West, South Yorkshire, North East of England, Central and Southern Scotland. The implementation of smoke control areas, the increased popularity of natural gas and the changes in the industrial and economic structure of the UK lead to a substantial reduction in concentrations of smoke and associated levels of sulphur dioxide (SO2) between the 1950s and the present day.














Exempt fuels and stoves

Any Broseley multi fuel stove can be installation in a Smoke Control Area but may burn only authorised smokeless coals. A list of approved smokeless fuels can be found on the DEFRA website.

Exempt appliances

Exempt appliances are appliances (ovens, wood burners and stoves) which have been exempted by Statutory Instruments (Orders) under the Clean Air Act 1993 or Clean Air (Northern Ireland) Order 1981. These have passed tests to confirm that they are capable of burning an unauthorised or inherently smoky solid fuel without emitting smoke.

Burning logs

Logs may only be burned in stoves which have been granted exemption from the regulations by the government through DEFRA. Exempt appliances are appliances (ovens, wood burners and stoves) which have been exempted by Statutory Instruments (Orders) under the Clean Air Act 1993 or Clean Air (Northern Ireland) Order 1981. These have passed tests to confirm that they are capable of burning an unauthorised or inherently smoky solid fuel without emitting smoke.
