Cold radiators, leaks, low pressure, noisy pipes, failed pumps, stuck valves and thermostats that do nothing. We find the cause rather than treating the symptom.

The boiler usually gets the blame because it is the part with a display on it. Often the fault is elsewhere in the system, and a new boiler would not have fixed it.
Radiators cold at the bottom and warm at the top is sludge, and bleeding will not help because it is not air. Cold at the top and warm at the bottom is air, and bleeding usually sorts it. One radiator that never gets hot is a stuck valve or a system out of balance. Pressure that keeps dropping is a leak, a failed expansion vessel or a passing pressure relief valve. Banging and knocking pipes is expansion against a joist, or a pump running too fast. Kettling from the boiler is limescale or sludge in the heat exchanger.
Thermal readings across the system, flow and return temperature checks at the boiler and at individual radiators, pressure and expansion vessel testing, and a look at the system water itself. A sample of the system water tells you a great deal about the condition of a heating system in a few seconds.
You then get told what is wrong, what it costs and what happens if it is left, before anything is spent.
Qualified engineers, a clean job and a fixed written price agreed before we start. We stand behind everything we fit.
Almost always sludge, which is iron oxide built up in the system water. Bleeding will not fix it because it is not air. It needs the system cleaning, and a magnetic filter fitting to stop it coming back.
Either a leak on the system, a failed expansion vessel, or a pressure relief valve that is passing and discharging outside. If you are topping up more than every few months, get it looked at rather than living with it.
Pumps are replaced rather than repaired. A modern high efficiency pump also uses considerably less electricity than a fifteen year old one running flat out.
Sometimes, depending on where it is and what has failed. We will tell you before we start.
That normally points at a diverter valve on a combi, or a zone valve on a system with a cylinder. Both are common and both are fixable.
