Frequently asked questions
Computer processing on the heata unit generates heat which is transferred into the water in your cylinder. This means that your existing heating system has to use less energy to get the water to temperature. Think of it a bit like solar thermal; when it's sunny it heats your water, reducing the amount of energy your main heating system needs to use. When the heata unit is processing it's having the same effect.
No, your existing heating system stays in place and the heata unit works alongside it. Your existing heating system will kick in less often as the heata unit has already provided some heat to the water. In some cases it will have provided enough hot water (your existing heating system won't kick in at all), in other cases your existing heating system might kick in to top-up the hot water.
A useful base load. If the heata unit ran all day it would deliver about 4.8kWh of hot water which is about the amount of hot water an average household uses. In practice the utilisation level will be lower and sometimes the water will be at temperature so the heata unit won't be able to run. We think it could deliver up to 80% of an average household's hot water, with good compute utilisation.
heata pays for the electricity used by the heata unit. Depending on your supplier, we’ll either directly credit your energy account, or your bank account. An accredited billing submeter with a readable screen is included as part of the installation, which we will read remotely to get the details for your credit amounts.
Yes, you’ll still have hot water as it works alongside your current central heating system, which will provide hot water if the heata unit isn't working.
The installation procedure is a larger version of how a standard tank thermostat is installed - we remove a patch of the foam insulation (taking it down to the metal). Then we attach our thermal bridge to that section, the heata unit is then connected to that. We’ve tested the process with British Gas, and spoken to a leading cylinder manufacturer who confirmed that following the approved installation process won’t invalidate your cylinder warranty. We will also re-insulate the area if the heata unit is removed.
