Non-condensing water heaters

The Andrews Water Heaters range of non-condensing water heaters are available in instantaneous and storage models.

These units offer a regular, reliable supply of economical hot water for a variety of applications.

To find out more about the Energy Related Product (ErP) Directive and the upcoming changes, view our ErP directive.

In December 2021, the government published updates to Approved Documentation L of Building Regulations relating to the conservation of fuel and power in existing non-domestic buildings.

From June 15 2022, the minimum heat generator seasonal efficiency for direct-fired water heaters will be 91% (GCV) for natural gas and 92% (GCV) for liquified petroleum gas (LPG). All indirect-fired water heaters will be required to achieve a minimum seasonal efficiency of 91% (GCV) for both natural gas and LPG.

So, there will be no opportunity to carry out like for like replacements with non-condensing water heaters except in exceptional circumstances.*

Our advice is to start planning now and future proof hot water systems with a condensing water heater.
