The advantages of tankless waterheaters are pretty straightforward - they save you space and money, and you will never run out of hot water, providing that you have fuel.
But there must be disadvantages? Well there are a few. First of all, there is the initial outlay. Most tankless waterheaters call for a larger initial outlay that, say, simply replacing your old water heating tank. The savings they make by only heating the water you need should repay you over time, however.
The other disadvantage is that they often call for a different fuel source - tankless gas hot water heaters are one of the most popular choices across the world. But not everyone has a local natural gas supply. Propane, in liquid form in large canisters, works very well, but again it is not ideal for everyone.
So if you do not want a gas tankless water heater is it still possible to move away from a tank-based heating system?
These days there are electric tankless water heater options that are convenient to fit as well as convenient to use - they just need professionally rigging up to the mains electricity supply.
