Helping you meet the challenge

We understand the challenges you face when designing homes to meet the requirements of today's building regulations, standards and guidelines.

When it comes to heating and hot water appliances, there are plenty of low carbon options open to you. But matters such as budget and practicality of installation can often prevent them being implemented.

That's where Alpha Heating Innovation can help.
Our GasSaver, FlowSmart and SolarSmart products enable you to maximise domestic heating and hot water system performance to achieve significantly improved energy efficiency and carbon emissions levels.

By utilising familiar heating technology, they avoid the need to radically re-think traditional heating system design, helping you to control building costs and project timings in the process.

The improvement over Building Regulations (TER) is in comparison to a compliant 88% efficient gas boiler where the Dwelling Emission Rate is equal to the Target Emission Rate in the test case SAP calculations

SAP Explained

The Government's Standard Assessment Procedure (SAP) is used to accurately assess the energy performance of new dwellings and is determined by the difference between the Target Emission Rate and the Dwelling Emission Rate. To comply with Approved Document L of the Building Regulations the DER must be less than the TER.

Each new property is assigned a Target Emission Rate (TER) based on the size and type of dwelling. This represents the amount of energy the building should consume when occupied. The Dwelling Emission Rate (DER) is calculated from the performance of the materials.

and products selected for the build. With the boiler and central heating system representing a significant part of the total energy used by a property, selecting the correct boiler will have a substantial effect on the DER.

The Alpha range of heating solutions will help ensure SAP targets are met while easily meeting the demands of a modern home. At Alpha, we offer valuable support with heating system design and SAP calculations as well as providing technical advice throughout the project and full product training
