Hi there, I often get quizzed over the true cost to the user of installing a new boiler. It seems to me consumers do not understand the costs around buying and installing a new boiler. You have companies who sell boilers and companies that sell and install boilers. You have local boiler installers as well national companies. You now even have websites such as http://www.boilersprices.co.uk/ideal-boilers-prices/vogue-combi/ trying to make sense of pricing within the sector! Can someone advise how pricing within the sector is regulated? It seems consumers have a trust issue with regards to engineers and pricing.
From my understanding there regulated through the free market process. Just remember, you get what you pay for.
If your question is the cost of the new Boiler + installation + the cost of the fuel it will burn, In X building , in Y given geographic location, with Z insulation level, compared with a different efficiency boiler over XX years at YY interest rate.
Then that is a very complex calculation that will change with each of the listed variables and dozens not listed.
The US government has released a computer program to do the calculation learning the program, entering the data, and interpreting the output will require about 30 hours of your time.
It is best for consumers to get several bids for similar equipment. Discard any bids more than %15 above or below the average as they are very likely flawed and then pick the remaining vendor you liked best.
When it comes to a topic as complex as a heating system, it is foolish to rely solely on bid prices to make a choice. Unfortunately for the consumer, the majority of contractors are very brief in their description of what they will provide for their bid. You have to look at the specifications, such as -brand and model- is it a reliable one? are parts readily available? Will the installer also maintain the system? Is he/she factory trained on that brand/model?
-Is the model chosen the best choice and most efficient for the application? (look at the yellow EPA efficiency label)
-will it include new ECM circulators?
-Is everything needed included? such as electrical or control wiring, permits, if a condensing boiler is a pH neutralizer included?
-will they check feed water chemistry and add treatment as needed? (many contractors are not paying attention to boiler water chemistry, which may not cause problems now, but can clog everything up in roughly 3-10 years)
-will the boiler or furnace be properly commissioned, as described in most IOMs?
Also keep in mind that the more complex the boiler (such as condensing and modulating boilers/furnaces), the more important it is for annual service, and the more the service and repairs will cost.
