What are these boxes in hot press?

Burti16

Hi All,

Just moved to my own house after living in small apartment where everything was so straightforward.

What are these control boxes for?

dbas

Motorized valves.

They control the flow of hot water to either heat your water tank, or heat your rads

Cool thanks!

Are they used when I only need hot water in tank ( e.g. in summer) or to control temperature by sending sufficient water to different heating zones? There are manual and auto switches on them

If it's anything like my setup, you have a timer somewhere in the house, probably downstairs on a wall.

Both the heating of the radiators and the water heating can be set to come on at whatever time desired.

Often there's a simple button press to heat the water for one hour (or the rads). Known in our house as "pushing the button" if it gets too cold during heating off times.

You don’t need to touch anything on the valves, they will be controlled by a timer clock which will be on the wall somewhere in the house.

The 2 beside each other are most likely for 2 heating zones Upstairs/Downstairs and the 3rd one to the left for the Hot water. As mentioned anbove there should be a timer/control somewhere in the house for these

The radiators in the upstairs section of our house heat up before the downstairs section. Do these boxes regulate that sort of thing?

Yes, that’s exactly what they do. You can set the timer on your heating clock for whenever you want either upstairs or downstairs on.

Not really they just turn one or the other off. SO you can have heating just downstairs during the day and not upstairs.

One looks to have a wire to the thermostat on the water tank so I'd say that controls hot water.

They other one controls heating if your house floor area is less than 100sqm.

Ad others have said you should have a programmer on your wall which you set, and that programmer tells your boiler to come on, and which of those valves to open

We only have one white box in our hot press area. We still have an issue with the upstairs radiators heating up before our downstairs radiators. This I don't understand.

We also appear to have two much hot water going in to our cylinder and would prefer to have it going in to our radiators. Is there a switch/button on the white box that can regulate this?

You need a plumber to look at that.

System might not be balanced right or the circulation pump might be goosed.

While they are there, get a price for getting another valve to control hot water to if you don't have it.

Thanks everyone. Very helpful. True, there are 2 manual thermostats which only have temperature setting in ground floor and the first floor. I can't seem to find 3rd one which for hot water only though

You must have some way of setting at what time the heating goes on and off.

There should be some sort of time clock somewhere, could be near the boiler.

the water in the tank has nothing to do with the water in the radiators.

The simplest way to describe it, is to think of a kettle. The element in a kettle heats the water. In your cylinder, the element is represented by a coil of pipe with water running through it that is heated at the boiler. The heat in this coil, then heats the surrounding water. To control the temperature of the water in the cylinder, you use the little thermostat that you can see cut into the green insulation surrounding the cylinder above. Once the water in the cylinder hits the required temp, it stops the boiler sending any more heat to the coil.

Turn this thermostat down if you have too much hot water
