Are condensing boilers more expensive to buy and install?”
– The extra cost is usually limited. A condensing boiler normally costs more to buy because it uses more expensive materials for the heat exchanger. Often the difference can be offset by grants from Energy Supply Companies, or local authorities, or via Energy Efficiency Advice Centres (EEACs). Installation will incur an extra cost as a result of fitting a condense drain, but this is usually a simple plumbing job. There may be flueing costs to ensure the plume does not cause a nuisance. Glow-worm offers a unique Plume Management Kit to solve this problem.
