Why Have a Condensing Boiler?

The answer to this question might seem obvious, but bluntly, a boiler provides you with an endless supply of hot water.

You may be among the people that have had to contend rinsing with cold water after the hot water run out at some point.  A modulating condensing boiler allows you to have an endless supply of hot water for your needs.

Another reason to install one is that they are pretty energy efficient. Coupled with their water saving capability, you might find that you are remaining with a couple of more dollars at the end month after paying your bills.


How to Choose the Condensing Boilers


The obvious feature that most people may be looking out for is speed. However, there are others more critical factors you should consider so you can finally end up with the best condensing boiler in the market. While speed is an important consideration, the average shower only needs about 2 gallons each minute. This means that you will pretty much be covered as long as you stick with a high-quality boiler.

The energy source is another important consideration, and there are two main ones – propane and natural gas. Some of the best boilers will run on natural gas, but some others will use propane. While those using natural gas will tap directly to the utilities, propane units will require you to keep several tanks in the vicinity so that you will not run out of the warm pleasure right at the middle of it.

However, they are not all bad. The fact that they are outside the utility system may ensure your continuity when the primary system requires repairs. This means that you may be enjoying your hot water while others are forced to wait until the situation normalizes.

You will also need to figure out where you want the boiler placed. The majority of users prefer them outdoors, but this might not be the best. There are issues like freezing and other problems associated with placing it outdoors.  Specially made outdoor models have safeguards in place. If not, then you must find space within your home. After all, they don’t take so much of it.

The majority of other considerations are now down to preference. The controls across models are the same and fulfill the same function. However, be wary of going for the cheapest models. Cheap will cost you more in the long run. If you happen to choose a good quality product, then it will last you a good number of decades.

If you think about it carefully, then you will note that that extra cash you pay for a boiler goes a long way. Don’t take that cheapest route. Be wise!



There are so many reasons as to why you should go for the best condensing boilers. For starters, condensing boilers are a real money saver. The best among them will save you on energy bills and water which is quite a good thing. Condensing boilers will also ensure you have a good supply of hot water to fulfill all your needs. Therefore, go ahead and install it, you will not regret you did.
