Are you thinking of getting a new hot water system for your house?
Most of the time when you’re looking for a new hot water system, you go online and type in how many bathrooms you’ve got. If you say two bathrooms, they’re always going to recommend a 20 or a 26 for Rinnai or Rheem Continuous Flow. But it all depends on your pipe sizes.
In this video, we’ll give you some tips in choosing one for your house.
Are you overwhelmed by all the options?
There are many types and brands of hot water systems. How do you know which one to choose?
Well, here’s some tips for you.
Basing on Your Old Hot Water System
If you’ve got a storage hot water system, which the bulk of houses do, there’s no point in getting a bigger one like the one you see in this video, unless you set it up properly with a manifold system.
Why?
If you have a Rinnai R26, you have your gas pipe that goes into the bottom. It’s 20 mil which is pretty standard on all of them. Then you have the larger water pipe that goes into the middle one. So it’s fed plenty of water to go in there. But then look, it’s getting pushed out into a smaller hot pipe.
If your whole main is this smaller hot pipe, there’s really no benefit at all putting a larger hot water system in. They would have been far better off just putting a 16 in there, because they’re made to have a 15 in and 15 out.
This has got a 20 in, 20 out, but the only way really to set it up properly is, if you’re gonna get a 26, is get a manifold system. Then they work absolutely sweet.
If you don’t know about the manifold system, we’ve got a video where we explain it all and even do a drawing on it. It’s pretty cool.
So, if you’ve got a storage hot water system, just get a 16 or something like it, otherwise you’re wasting your money. Or, if you want a bigger one, where it runs correctly, put a manifold system in.
