Heating & hot water

Heating that warms the whole house

Powerflushing, balancing, radiators, cylinders and controls. The work people are often told needs a new boiler when it doesn’t.

Diagnosis

A cold house is usually a system fault

A boiler that fires and a house that never warms up are two different problems. Replacing the first does not fix the second, and plenty of people find that out the expensive way.

Sludge

Black magnetic debris collecting in radiator bottoms and pipework. Flush it, then fit a filter so it does not simply come back over the next two winters.

Balancing

Setting the lockshields so the far end of the house gets its share. A couple of hours of work, no parts, and it fixes more cold rooms than anything else we do.

Controls

Zone valves and a sensible programmer instead of one thermostat in a draughty hallway deciding the temperature of an entire house.

Half the house cold, the other half roasting?

Usually balancing or sludge, and usually not a new boiler. Ring and we will tell you which.

Hot water

Cylinders, vessels and the shower that dies

If the shower drops to a dribble when the kitchen tap runs, no amount of boiler replacement will fix it. That is a stored hot water question, not a boiler one.

  • Unvented cylindersMains pressure hot water at every outlet, so two showers can run without a fight.
  • Expansion vesselsThe part that fails quietly and makes the pressure relief weep. Replaceable on its own.
  • Immersion and controlsBackup heating and timers set so you are not heating a full tank overnight for nothing.
  • Annual cylinder checksUnvented cylinders have safety controls that need checking, same as a boiler does.

FAQs

Heating questions

Why is one radiator cold at the bottom?

Sludge. Magnetic debris settles in the bottom of the radiator and the hot water flows over the top of it. Cold at the top with a warm bottom is trapped air instead, which bleeding fixes in a minute.

Why is the top floor always coldest?

Balancing, usually. Radiators nearest the pump take the flow first unless the lockshield valves are set to share it out. On Sheffield’s taller stone houses the top floor is furthest away and suffers first.

What does a powerflush actually do?

Pumps a cleaning solution round the system at pressure to shift the sludge out of radiators and pipework, then refills with inhibitor. You need it if radiators are cold at the bottom, bleed water runs black or the boiler keeps cutting out. You do not need one just because it was on a boiler quote — ask to see the system water.

Can you move a radiator?

Yes. With a suspended floor it is usually straightforward. Solid floors mean either running in the wall or accepting surface pipework, and we will be upfront about which before starting.

Do you fit cast iron radiators?

Yes, and they suit a lot of the older property here. The things to check are the filled weight against the floor and fixings, and whether the valves and tails match. Restored ones need the same checks as new.

Should I switch to a cylinder?

If you have two or more bathrooms in regular use, very likely. Stored hot water lets several outlets run together. It costs more and takes space, but it is the only thing that fixes a shower that dies when someone runs a tap downstairs.

Can you zone the heating?

Yes. One thermostat in a hallway controlling a three storey house satisfies nobody. Zone valves and proper controls let you heat the parts of the house you are actually using.
