Warmflow
Warmflow has been established as a privately owned company for over 30 years and is now one of the UK’s leading manufactures of oil fired appliances. At the core of our success is a commitment to providing high quality, value for money products and after sales service.
All ‘HE’ products have been independently third party tested and accredited to ensure compliance to relevant European standards for efficiency and construction and in addition to ensure that we maintain our own in house quality standards, we also have in place a BSI approved monitoring system certified to ISO 9002.
making an environmental investment
Until now, we have focused our attention on producing high quality conventional boilers but in an effort to help save precious fossil fuels and reduce harmful C02 emissions we are now proud to introduce the new HE range of high efficiency boilers.
With efficiency levels of up to 97%, HE boilers easily exceed the minimum requirements of SEDBUK rating A, and therefore operate more economically in comparison to a conventional boiler, providing much-needed savings in running costs and helping to significantly reduce the time taken to pay–back the money you have invested in your HE boiler.
unique features and benefits
HE boilers are suitable for use on most types of fully pumped heating and hot water systems and are ideal for systems that have been designed to operate with a low return water temperature i.e. under floor heating.
Available in 3 models standard, sealed system and heat store combi and outputs from 15 to 32k.w all HE boilers are suitable for use on conventional flue or low level, high level or vertical balanced flue using the 125mm HE ‘easy fit’ balanced flue system.
Ease of installation
Warmflow takes pride in being a company with a reputation for producing quality products that are easy to install and maintain and as you would expect the HE range fits nicely with this philosophy. Incorporating the latest Riello RDB 2.2 burner and an easy-clean front servicing secondary heat exchanger,* the HE range is proving to be extremely popular with both heating and commissioning engineers.
