Electric Hot Water Cylinder Repair

£300

Elephant And Castle, Greater London, SE1

20th Jun 2026

Issue: Intermittent Hot Water Failure - Heatrae Sadia PremierPlus Unvented Cylinder I have a Heatrae Sadia PremierPlus unvented electric hot water cylinder with an external Aquasystem expansion vessel. The issue is intermittent: * Sometimes there is no hot water at all. * The system occasionally starts working again by itself. * Sometimes I can get it working by turning the electricity off and on or repeatedly using the Boost function. * When it starts working again, it can take several hours before hot water is available. * No obvious leaks are present. * The expansion vessel appears intact, but I am unsure if it is related.

We’ve received an excellent service from Egzon. He was very quick to spot the issue and organize the fix for it. Highly recommend.

Electric hot water cylinder installed

£500

Shacklewell, Greater London

25th May 2026

Looking for someone who can install and self-certify a hot water cylinder in our garden room. As this is for secondary use we're looking for around 100 litre tank. Nothing fancy as we're keen to keep costs low due to it being a garden room. The electrician has already set up the fuses and wiring ready to be connected. We are working on the pipework for the bathroom setup over the next couple of weeks so can also build the waste for the hot water cylinder if that is helpful.
