I have a Gloworm boiler and I have got a plumber to look at it he said the heat exchanger needs replacing. Also the diverter valve. If the heater exchanger was not working would I still be able to get the heating to work?
It sounds like a diverter valve isn't working wisely yet fee to repair/replace can variety with the make as some makes could be repaired by potential of fixing the motor interior the valve that's plenty greater fee-effective than a valve substitute. Pump can be enjoying up,attempt finding the fee change interior the terminal cover, it is two velocity with a change or 3 velocity with a rotary dial and adjut it to work out in case you may hear or sense any difference.New pump on my own(in a container) is around ?ninety + VAT.
If I were you I would get Gloworm out on a fixed price repair. Look at how much this man wants to charge and compare it with the fixed price repair cost which will cover you if they have to come back for any reason within a month. You don't specify the model or age which would be helpful. Swiftflow Compact CI Energysaver combi CXI Flexicom Ultracom would be some possibilities. It is actually quite common for the plate heat exchanger to get blocked with magnetite if the system has not been cleaned and inhibited properly.
A Heat exchanger on a Gloworm boiler should be good for 10 years at least. I would get another plumbers opinion before paying for a part you may not need.
It is possible that the plate heat exchanger is blocked with sludge or lime scale.The divertor valve may also be bunged up or may be needing a diaphragm.If the engineer insists on replacing the parts then make sure the boiler and radiator system is treated with a cleansing agent and an inhibitor.Ask for a quote on the work needing done and consider replacing the boiler as it might be more economical if the appliance is old.
If this is a boiler (Not a forced-air furnace), then the heat-exchanger is either good or it is bad. If it is leaking and cannot be easily repaired, it is bad. If it is not leaking and you are getting proper heat, it is good. Similarly with hot water. It is just possible that the heat exchanger has become clogged with scale or debris - this would be highly unusual. The diverter valve is another story. They fail fairly commonly. But this taken with the suggestion on the heat-exchanger makes me think he might be fishing. Get a second opinion, for sure.
