The first thing you need to check is the capacity of the boiler. The capacity of a boiler is usually measured in BTUs (British Standard Thermal Units).
These are the amount of energy units required to heat one pound of water and raise its temperature by one degree Fahrenheit. The amount of BTUs you can consume depends on the climatic conditions.
For instance, during winter, a one foot square space consumes up to 50 BTUs. The number drops to 35 BTUs and 20 BTUs in spring and summer respectively.
This means that if you house has a 1,000 square foot space, you will need up to 50,000 BTUs during winter and 35,000 BTUs during spring.
Consider the Venting System
You need to check your home’s venting requirements. This is important because there are a wide variety of boilers out there, each designed for specific venting orientations.
For instance, there are boilers that are designed to expel waste through chimneys. There are others that are designed to exhaust using fans. In this case, the fans push the exhaust through the roof or side wall.
The choice of boiler depends on your house planning. If you plan to use the boiler in a closed space such as crawl spaces and closets, you may need a boiler designed to exhaust through a chimney.
If you are planning to use it in an open space, then you can use one that comes with a fan.
Though it is good to have a warm and comfortable home during winter, you want to make sure you are doing that at a lower cost.
That is why it is important to consider the energy efficiency rating of the boiler. Boilers are rated using the Annual Fuel Utilization Efficiency (AFUE) modulation. This modulation provides you with a rough overview of how well your boiler can convert fuel to energy.
A good domestic boiler should have an AFUE rating that ranges between 95 to 100 percent. So check the boiler to see its rating before you buy it.
Buying a boiler is a big financial decision. You expect it to serve you for a long period, preferably 10 years or more. A good boiler should be reliable and dependable.
Ask your friends or any HVAC expert which boiler they consider reliable. Read articles about boilers and check product review sites to see what people say about different kind of boilers.
It is difficult to determine whether a boiler is reliable or not by just looking at it. You have to do extensive research and ask around.
Look at the manufacturer’s manual to see the mode of installation for your boiler. If the instructions seem too sophisticated, then ask someone qualified to help you out.
Make sure you hire someone who is experienced and skilled to uninstall the old boiler and replace it with a new one. Never attempt to install the boiler on your own if you don’t have any experience.
