Condensing Boiler Vs Tankless Water Heater

For instance you want to know the climate conditions around the house and whether or not there s enough space for the units.

Condensing boiler vs tankless water heater.

They are slightly more expensive to manufacture but are over all on par with non condensing tankless water heaters that need to use expensive stainless steel venting materials and are less efficient about 80. Conclusively condensing tankless water heaters are very efficient up to 98 real energy savers and use inexpensive venting material. Condensing boilers are sometimes more energy efficient than other types as they retain the heat that escapes the flues for venting toxic gases produced when heating water with gas present in non condensing boilers. When efficiency is key the condensing models outperform their kin coming in at 90 percent efficiency compared to the 80 percent of non condensing tankless water heaters.

I really like tankless but i still say boilers are boilers and water heaters are water heaters. Tankless hot water heater a smaller less efficient less volume non condensing boiler. Condensing condensing boilers are not a type of boiler but more of an attribute that a boiler can have. In yet other cases the right tankless water heater will do a good job since it only heats the water when you need it and it provides it quickly.

Condensing boilers are much more efficient in energy use and maintenance but are also more expensive to buy. It is already established that condensing type of water heater is more efficient than the non condensing type for about 10 to 15 percent. On the other hand condensing tankless water heaters may reduce the expenses for making it able to run overall. That said it is a cheap btu.

Go with the boiler. They function similar to the muchkins and copper fin boilers you might be able to pay for two tankless v s one 90 boiler of the same btu rating. While most tankless heaters are compact boilers could consume more space. In other cases you can certainly use a water heater and it will also be more efficient than some boilers.

If a tankless was condensing and had better heat transfer elements than it would be called a boiler. Both choices are more efficient than electric models. A small boiler is a very big tankless. Condensing boilers work similarly to a conventional boiler in a lot of ways.

I had the same question myself. While tankless water heaters run more efficiently than storage tank water heaters replacing a tank water heater with a tankless can be expensive and the payback time can be longer than the warranty. Actually had to speak to hydronic technicians. Deciding between a boiler or a tankless water heater depends on several conditions.
