Efficiency is key

Having an efficient home can have a significant impact on your heating bills, as well as the size and cost of ground source heat pump required.


The more efficient your home, the less work your heat pump has to perform in order to deliver the heat required, which means less electricity consumption, and of course even lower electricity bills.


An efficient home can also ensure you get the very best from the Renewable Heat Incentive (RHI), generating you a healthy sum of money and return on your investment every year for 7 years.


So how do you go about making your home as efficient as can be, and what impact will this have on your heating system?

Reach for the stars!

Selecting whether you have underfloor heating or radiators, and what floor covering you use, can all effect what the industry call your ‘system star rating’, which is clearly explained in the MCS Heat Emitter Guide.This document is an excellent resource to support good design practice.


The more efficient your selections, the higher your star rating, which ultimately means lower fuel bills. Typically well insulated homes with underfloor heating downstairs and radiators upstairs (over-sized if a renovation) return the best results.


The Star Rating relates to the heating system flow temperature.  For underfloor heating, you can typically expect a higher Star Rating, e.g. 5 or 6 Star; if you are using over-sized radiators, you will have a less efficient system, typically producing a 3 or 4 Star Rating. 


If you are using a high temperature heat pump with standard sized radiators, you should expect a 1 or 2 Star Rating.

The Heat Emitter Guide

To identify the most efficient system for your project, and your Star Rating, we recommend you refer to the Heat Emitter Guide.


This free, handy guide, will assist you or your installer to size an efficient heating system for an existing or new build project.
