Hot water too warm

by Cha » Sun Jan 31, 2010 5:17 pm

The temperature of my hot water is far too high for the safety of children
(probably about 80 - 85 deg.C)
My HW cylinder is gravity fed, indirectly heated.
What is the simplest method of controlling the temperaure of the hot water?

Any advice most welcome.
Thank you.

Cha,
If you do not have a thermostat on the hot water cylinder then turn down the thermostat on your boiler.

Thanks, Stoneyboy.

But doing as you suggest, would make the radiators colder, as well.

What's involved in fitting some type of thermostatic valve to the HW cylinder?

Stoneyboy is right as that is the only way to reduce the water temperature. The downside is it will make the radiators cooler too.

Adding a thermostat to a gravity system is not easy as it requires significant changes to both the electrics and plumbing. Cost may be a prohibitive factor.
