Tankless Water Heaters

I need some input.

Do any of my readers use a tankless water heater system in their home? I have been fascinated by the idea of a system that only heats water on demand for years now, but the last time I looked into having one installed, the plumbing company said we would have to have our entire house replumbed. I think it had something to do with the 2-storey style of our home or something. Honestly, I did not understand. When you hear advertising for tankless water heaters, it always sounds like making the switch is simple.

I’ve known people who have small units under their sink, which is pretty handy for dishes or a cup of tea. I’m talking about a whole house unit, though. I want to know what it would take to convert my house over to that kind of system and also how much hot water I could expect a typical unit to deliver to my home simultaneously (like if someone were showering while I was washing dishes).

I have seen plans for homes that involve just installing a small unit for each location throughout the home that would need hot water. I have heard this is the most energy efficient way to go, but I have to wonder about the initial cost of upkeep of a system like this.

This is a topic I cannot get out of my mind, but when I do the research myself, it seems quite complicated. Input from anyone who has actually used a system like this would be much appreciated.

A great site to learn about tankless water heaters and how to properly size one for your home is www.lowenergysystems.com. While the initial cost to install a tankless water heater is more than a tank-type heater, you will see measureable utility savings over the lifetime of the unit. Tankless water heaters require Category III stainless steel venting, which is pricey, but well worth the investment in installing a tankless water heater.
