Reducing heating bills in schools!


The Problem

Heating is the largest utility cost in the majority of schools. On average a school spends £44 per pupil on heating in a single calendar year which accounts for around 60% of its total utility outlay. As the largest utility cost, it also has the biggest potential to be reduced and to save school money whilst helping the UK achieve its ambitious carbon reduction targets.

Common practice to reduce heating bills is to turn down your thermostat but this is not always practical as schools have to adhere to the minimum classroom temperature requirements set by the Education Regulations for School Premises.

The Solution

We’ve teamed up with UK business EndoEnterprises because we think they have THE product to help. EndoTherm is an award winning central heating additive which is independently proven to reduce heating consumption by up to 15%. EndoTherm has recently won the 2016 CIBSE: Building Performance Awards, Energy Saving Product of the Year.

EndoTherm is installed into any water based heating system at a 1% concentration. With a quick easy install, zero maintenance and proven longevity, EndoTherm is an ideal solution to reduce the heating bills within your school.

What we also love is that EndoTherm is 100% organic, this means the embodied carbon (carbon used to manufacture the chemical) is very low. A typical EndoTherm installation will offset this embodied carbon in just 1 day!

Case Study

Two Eco-Schools have already seen the benefits of EndoTherm including Stowe School in Buckinghamshire. They tested EndoTherm in their swimming pool building (Air Handling Unit) as this was a major user of fuel. EndoTherm was installed in December 2015 and the fuel usage was compared with the same 3 months as the year before.

Overall the system reduced consumption by 21.9%. This was a saving of £635 which meant the initial investment was paid back within the trial period. For more information click here.

Get Involved

A great way to engage your Eco-Committee on energy saving is let them run an EndoTherm install themselves. Conduct simple experiments to see how EndoTherm works, calculate your schools’ requirements with potential paybacks and witness the product’s simple installation. This fits perfectly in to the Monitoring and Evaluation part of your Eco-Schools seven steps!

EndoTherm have created a brilliant curriculum-linked guide and practical experiment resources to help you embed Eco-Schools work in to your lessons! Download them for free here:
