Fine, but please explain why. But it wouldn't do what I want. I am currently sitting in my office, which is at a comfortable temperature. My bedroom is at the same temperature, but it doesn't need to be this warm at this time. How would your £42 suggestion allow me to have my bedroom...

So you know my system better than I do? The only supply to the system is 3-phase. There is no separate single-phase supply to any control system. Anyway that doesn't help with running different rooms at different temperatures during the day. At this point it may be instructive to look back at...

My objective is to reduce heating costs. Is a new system going to work so much better that it could pay for itself in a reasonable time?

1. 100% of the people in the UK have a much milder climate than we have. When was the last time you saw temperatures of -40C? 2. It takes more than a £30 timeclock to control the 3-phase supply to the GSHP. 3. No simple timeclock is going to allow the heating to come on if the...

Yes, I can do that. Indeed I do do that in rooms that are rarely used. With the best will in the world though, that isn't a solution for rooms that are in regular use; adjusting dozens of rads every day is not something that gets done. The house is at the temperature we want. Sure we could...

Fixed views? Well yes, in so far as I know the system, and what I can change. Why would I want to vary the whole house temperature? I want the rooms that are in use to be at the temperature we find comfortable. I only want to drop the temperature in unoccupied rooms. 3 of us live here. No, I...

Thanks for your comments Alec. I may well have missed the point; perhaps that is why I am here :wink: I do understand the need to avoid the heat pump needing to run its auxiliary heating mechanism, but I still think it should be possible to reduce heating costs. Currently the whole house is...

The heat pump has a system to relate the flow temperature in the CH to the outside ambient temperature. This is done by defining a so-called curve (actually 2 straight lines) like a graph. The pump runs to this 24 hours per day. I can change that curve to suit the house but really that is a...

Why?

No, or at least unlikely. I am thinking about UK suppliers.

The heating system in our large old house is a ground source heat pump feeding a mixture of old cast iron and slightly more modern (but still old) pressed steel radiators. The pipework is iron. There is no zoning, and I am not even sure if this is a single or twin pipe system. All the pipe runs...

Perhaps you have never used a cash machine. You can't just enter the amount of money and withdraw it. You have to remove your card before the machine spits out the cash. So the instructions: 5 Remove card and receipt 6 Drive off will leave your cash sitting in the machine

Although I am a bloke I can see the advantage of the female version. At least they get some cash. The male procedure seems to leave the requested cash in the machine.

We have a 650 litre horizontal tank which was already in place when we moved here. This tank is no longer our primary source of hot water. We use it as a tempering tank before a new 300 litre upright tank. The upright tank is a lot better, but then it is also much newer and modern, so not a fair...

The Ecclesiastical Insurance Company specialises in this area, with some policies aimed specifically at Anglican churches. I assume they must have customers or they wouldn't stay in business. The only reason I know about them is that, decades ago, they offered me a job which I didn't take. I...
