There are new companies, new models, and new options available that you’ll have to sift through to find the perfect gas boiler replacement for your home.

What Size Gas Boiler Replacement Do You Need?

It now takes into consideration the age of your home, the energy efficiency of your windows, your insulation, and other factors that will affect how big of a boiler you need to heat your home. Of course, if your boiler will be used for heating water for the home as well, then the number of bathrooms and the number of appliances that use water will have to be factored in as well so that the boiler isn’t too small for the home. The square footage is still a factor, but it’s a smaller factor than it used to be. You can search for boilers by size or you can talk to a professional boiler installer about the most common sizes so that you know what would be available for your home.

Comparing Gas Boiler Replacement AFUE Ratings

It is required by law to be visually placed somewhere on the boiler so that consumers and technicians who come in contact with the boiler know what the AFUE rating is, or was when it was purchased. While an AFUE rating doesn’t take into consideration the heat loss from factors inside the home, it does take into consideration the heat loss from within the boiler and the exhaust directly from the unit itself. This rating is important as it tells you how efficient the boiler is. Most replacement options have AFUE ratings of upwards of 90%, which tells you just how far technology has come. If energy efficiency or low carbon footprints are high on your list of requirements for a gas boiler replacement, then having a high AFUE rating should be high on your list as well.

What Functions Will Your Gas Boiler Replacement Have?

Knowing what functions your boiler will have in the home is very important, as many replacement boilers end up taking on more work or less work than their predecessors because of changes made to the home during the replacement process. If your boiler will take on added responsibilities, such as heating water for the home, then you may need to replace your boiler with a larger one than you had before, and you may need to change the kind of hot water heater or hot water storage tank that you have as well. You may also have to change the type of hot water heater you have if you are taking the responsibility of heating hot water away from your boiler and your replacement won’t be heating water for the home. If that’s the case, then you will have to find another way of heating water for the home that is just as efficient as or more efficient than it was with a boiler.

Evaluate the Total Cost of Each Gas Boiler Replacement Option

To find the best deal overall, find the total price of each unit. The total price should include any installation costs, the cost for extended warranties if you plan on purchasing them, and any other costs included in getting your new replacement installed. Each unit will also have a size based in BTUs, or British Thermal Units. If you take the total cost of the unit you are considering purchasing and then divide it by the BTUs of the unit, you have the cost per BTU. If you find the cost per BTU for each unit you are considering, then you can compare them side by side as to which units will give you more heat for the cost of the boiler. This is a great way of determining the cheapest value of the boilers you have already determined would be a good fit for your home.

You need to find the right size boiler for your home, you need to compare the AFUE ratings of each boiler model that is in the proper size range, you need to know what responsibilities the boiler will have, and you need to evaluate the total cost of each option before you can make a decision about a replacement. A replacement is inevitable at some point if you own your own home and you have a gas boiler. While they do have long lifetimes, they do not last forever, and replacement of any home heating appliance will be necessary at some point in time. By following these guidelines to finding the perfect gas boiler replacement for your home, you can ensure that you get a great deal on a new boiler while you also make sure that your home stays warm and you have hot water for years to come.
