Review on Efficient and Reliable: GIRARD 2GWHAM Tankless Water Heater by Eric Currie

I live in an RV about 300 days a year. The worst thing about living in an RV is a 3 minute shower plugged into a 2.5 GPM water heater. This item is a real life saver! It produces hot water in about 5 seconds and runs indefinitely. Well at least I personally used mine for about 35-40 minutes and it continuously dispensed water at the correct set temperature. The instructions specifically state "Professional Installation Only". However, if you have a basic knowledge of plumbing and 12vdc systems then you have all the knowledge needed to install this unit. Please note that installing this device yourself will most likely void your Girard warranty. I've personally weighed the difference between a $590 install and the cost of buying a new device and figured I'd rather install the device myself and use about $75 of Home Depot supplies if it were someday in the future I'll just buy another one and pocket his. So far I'm very impressed and will definitely be installing it in all future motorhomes.
