Not happy with with new unvented system, although it works fine. Shower pressure issue

[SJB060685]

Kingspan came out this morning to inspect the installation and they said the installation had been done to a good standard and there were no problems with the new set up. They would be happy to honour the warranty and commence the service plan.

Only question I have is.. the hot water thermostat was set at 65degrees before. The engineer said this was probably be a bit over kill the water would be quite hot to be able to touch and not so energy efficient. He set this to 55degrees. assume this is ok to do?

Stored HW should be heated to 60°c to kill off any legionnella bacteria.

As above needs to be coming out of the taps / stored at 60dc

Like every decision that trades off risks (salmonella vs scalding) there is no right answer. The consensus in the UK seems to be that 60°C is the sweet spot. The heat losses from a modern tank are so low anyway the savings are barely worth considering.

He did say this too. He said as the water is constanly flowing and in use the risk is super low. It would be more of an issue in static/stagnent water for long periods of time with no use.

Happy with your shower experience now and that’s good of Kingspan

Temp now adjusted to 60 degrees as per recommendations. Thanks all

@ShaunCorbs yes- shower is back to being amazing. Water has solid powerful output and plentiful. I’m back to taking longer showers

Good of Kingspan yes- naturally there’s cost involved but it’s all within the service plan.

I’ll let them service it for the next two years at least as they cover all parts and labour within that time... then after that I’ll see how much a service is from an independent.

If it’s similar or not much more will just let Kingspan do the service as I get to spread the cost
