In other cases you can certainly use a water heater and it will also be more efficient than some boilers.
Condensing boiler vs tankless water heater.
Conclusively condensing tankless water heaters are very efficient up to 98 real energy savers and use inexpensive venting material.
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.
While most tankless heaters are compact boilers could consume more space.
Tankless hot water heater a smaller less efficient less volume non condensing boiler.
That said it is a cheap btu.
Both choices are more efficient than electric models.
Condensing boilers are much more efficient in energy use and maintenance but are also more expensive to buy.
A small boiler is a very big tankless.
Condensing boilers work similarly to a conventional boiler in a lot of ways.
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.
On the other hand condensing tankless water heaters may reduce the expenses for making it able to run overall.
Condensing condensing boilers are not a type of boiler but more of an attribute that a boiler can have.
Go with the boiler.
If a tankless was condensing and had better heat transfer elements than it would be called a boiler.
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.
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.
It is already established that condensing type of water heater is more efficient than the non condensing type for about 10 to 15 percent.
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.
Deciding between a boiler or a tankless water heater depends on several conditions.
I had the same question myself.
In some cases a boiler is needed and only a boiler will do.
Actually had to speak to hydronic technicians.
For instance you want to know the climate conditions around the house and whether or not there s enough space for the units.
