I have quotes to replace a heat exchanger on a boiler. The boiler is 16 years old and a couple of the companies have suggested replacing the whole boiler. Are there other components that are likely to fail soon after a heat exchanger? Am I likely to extend the life of the boiler significantly by replacing the heat exchanger only?Thanks to all for any help or advise
Unless you plan on upgrading to a higher efficiency boiler, you might as well just change out the heat exchanger. It's roughly half the price of getting a new boiler.
A leaking warmth exchanger is amazingly risky! It signifies that the metallic has corroded to the point of failure. The leak will by no ability get any more desirable effective, it is going to truthfully proceed to strengthen worse. 3 bar of stress interior of reason important. a million bar is the equivalent of one million environment or 14.7 kilos in keeping with sq. inch. 3 bar then is an identical as almost 40 5 psi. each sq. inch of the nice and comfy temperature exchanger then has almost 40 5 kilos of stress attempting to push its way by the metallic. The water in the nice and comfy temperature exchanger will be drastically hotter than 212 degrees F lower than 3 bars of stress. If the metallic fails the water will flash to steam, increasing in the approach. that is like igniting dynamite. it may and could do significant damage on your position. you want to have a qualified boiler provider technician are available and have a seem on the device. it truly is achieveable that you'll want a sparkling warmth exchanger. it truly is likewise achieveable that a gasket is failing and needs to get replaced. yet another danger is that water vapor in the combustion gases is condensing because it provides up warmth in the nice and comfy temperature exchanger. those issues each and each require a diverse restore. Be secure and make contact with in a technician to ensure the precise nature of your worry.
