Baxi Ecogen FAQs

Q Where can the Baxi Ecogen be fitted?

A The Baxi Ecogen must be mounted on a wall that is able to accept the weight of the appliance when full of water. Consideration must be given to safe lifting of the boiler from floor to wall, including manoeuvring over worktops. Baxi recommends carrying out a site survey.

Q How noisy is the Baxi Ecogen?

A The Baxi Ecogen noise pressure level is less than 46dB at a distance greater than 1m directly in front of the appliance, in line with a conventional boiler.

Q What are the maintenance requirements for the Baxi Ecogen?

A The Baxi Ecogen should be serviced once a year by a competent engineer (eg Gas Safe registered engineer who has undertaken the Baxi Ecogen training course). The Stirling engine is sealed for life and so servicing and repair is similar to a conventional boiler.

Q Is planning permission required?

A No. Planning permission is not required for the Baxi Ecogen.

Q Does the Baxi Ecogen comply with Building Regulations Part L?

A Yes. The 2006 Building Regulations require no worse than regular Band B boiler carbon emissions. Ecogen has lower carbon emissions than a regular Band A boiler. 5.3 tonnes of carbon per annum (Ecogen) vs 6.1 tonnes of carbon per annum (Band A boiler).

Q What is the heating plant emission rate (HPER)?

A Unlike regular boilers, the carbon credentials of the Baxi Ecogen are not given in terms of a seasonal efficiency (ie SEDBUK). Instead, a Heating Plant Emission Rate (HPER) is given for the appliance in a particular property. The HPER gives an indication of carbon emissions of the Baxi Ecogen in a specific property and is given in kg CO2 per kWh. Because the Baxi Ecogen is heat led (generates electricity only when there is a demand for heat), the HPER is given for each kWh of heat generated, but the carbon value is for both heat and electric generation.

Q Does the Baxi Ecogen need registering like a normal boiler?

A Yes. The installer registers the Baxi Ecogen installation with Gas Safe in the same way as a standard boiler. A Building Regulations certificate will then be issued to the householder in the normal way, to go with the Benchmark Certificate.

Q How is the Baxi Ecogen treated within SAP?

A There is a section of SAP dedicated for micro-CHP known as 'appendix N'. SAP Appendix N cross references the performance data from the SEDBUK database. Performance data appears in a dedicated micro-CHP section of the SEDBUK database.

Q What is the SAP benefit of Baxi Ecogen?

A For most new build houses, using the Baxi Ecogen can assist in achieving CSH level 3.
