I used an undersink water heater to provide sufficient hot water for

Sometimes the simplest systems are the best.

Then you should have had night store electric heating too. ;-)

Something I detest. I have never known anyone to experience gas CH
have a good word for night storage radiators.

They're all right if you know how warm it's going to be the following
day and you want to heat the place 24 hours. Maybe the modern storage
heaters are better, but I found it hard to control the output of
stored heat.

A gas system boiler without any pumps or water valves is as simple
as you can get.

No pumps or valves? They must be quite complicated inside.

A simple system boiler has a variable speed fan and a modulating gas
valve. No other moving parts.

Pump?

Ok I confess to meaning a heat only boiler such as:

These don't have a pump, or any of the other over priced paraphernalia
that can go wrong.

I had my system pump replaces after 29 years. They don't go wrong that
frequently.

I've had a pump fail, and a neighbour has gone through 2 3-port diverter
valves. It's pot luck. If it's outside of a boiler then it can def be a
DIY job.
