Rinnai on demand hot water installation part 1

I got tired of constantly paying the power company for heating 120 gallons of hot water. It was something we needed when the kids where in the house ,but now that they are gone we decided to switch to an on demand hot water system heated with gas. see you later electric.
This eliminates that big hot water tank as well as that extra meter on the house that just seems to never stop spinning About $45.00 per month this is a cost recovery for the system in 2 years
It will cost close to $2000.00 to install complete when done but I also don't have any more cold water problems even in a power failure because the system runs on mili amps you can use a battery to keep it going.

This is the new heating unit for hot water REU-VC2025FFU-US-P
on amazon for 670.00 along with it at the minimum you will need a ubbink 21 inch universal non condensing kit (long) at 35.00 and a Webstone 3/4 ips union kit  5443WPR

Choosing your location is critical , if you end up with a long exhaust run you will need a condensing drain and the exhaust extensions are very expensive and can increase the cost of installation by almost 200.00 OUCH
I find the valve kit a bit high priced also for what you get but its designed for the heater so if you don't want to go chase parts its still the way to go

The system will replace the old 120 gal hot water heater and the lot water meter it should save about 40.00 per month in electricity and increase the gas consumption by 2.00 I like that trade off

.These items are going away

It took about 4 hrs to determine where to install the unit and set up a frame. I only had one spot in the basement to work with and i lost my old coal shoot as a result which was also my basement venting but that can be modified and is not a big problem

When you do the exhaust vent don't use the pattern on the box use the collar as a hole pattern, the vent hole gets too big and you end up filling it with insulation to make it tight again.

In part 2 of this we will install the new gas line to run this heater and also set up for the new furnace and re route the kitchen stove line.
