Get to know your Cosy heat pump

It’s normal for heat pumps to create water while operating but this should drain away easily from the drain pipe fitted to the back of your Cosy. If you’ve found a puddle of water, check that there’s no obvious debris or blockage of the drain pipe, and carefully clear away any you do find. If you can’t see anything, or you’ve spotted a leak, contact us - don’t try to fix it yourself.

This could be a sign of a leak and your heat pump needing to work extra hard to heat your home. Don’t try to fix the leak yourself and give us a call straight away and we’ll arrange for an engineer to come and fix the problem.

You’ll get used to the way your heat pump sounds when it’s working as it should. But sounds that are unfamiliar can tell you that your heat pump needs some attention.

Loud gurgling, grinding or squealing sounds are likely telling you that your heat pump is struggling and has a problem that we’ll need to fix.

In colder weather your heat pump will be working harder so it may seem louder than usual. This is especially true if it’s one of the first cold days of the year.

This could be due to loss of electricity supply. Check both the indoor and outdoor units are switched on and check your app is connecting to the system. Next, check your circuit breaker box for a tripped circuit. If there’s not an issue with either then contact us for advice.

If the heat pump is running constantly your thermostat could be set too high. Check the thermostat temperature and that they’re working correctly.

Make sure you check your Cosy Pods to make sure the “Boost” function isn’t on. If it isn’t, take a look at your Cosy Hub in case there are any fault indications showing. If everything looks to be working with your thermostat and Cosy controllers, contact us for help.
