i bought a tank-less propane water heater on e-bay for $52 brand new my question is how do i vent it? i want to put it on a divider wall in a lower bay. i was thinking of venting it out to a hole in the door with a furnace exhaust cover on the door so when the door closes the pipe would go right through the hole. any better ideas? | ||

If you don't already have them, I would go to the manufacturers website and get their installation instructions and follow them very carefully. Remember that you must also provide air to the unit as well as exhaust the fumes. | ||

not to worried about air as my seals in the bay are rather drafty.... also the manufacturer doesn't seem to have a website? | ||

Tom, Please look at the thread "Water Heater," about 8 posts down. Then tell us the BTU rating of yours, and anything more that you can. Then we'll try to help. G | ||

Tankless water heaters use a tremendous amount of LP and put out a tremendous amount of heat compared to tank heaters. You will need a lot of vent capacity. I was going to install one in my house but my LP line from my tank is too small (3/8", Min size is 1/2"). This gives you an idea of the heat involved. | ||

I have a tankless water heater at home and we are very pleased with it. However, it is 140,000 BTU, natural gas and we are in Florida where the incoming water is close to 70 degrees all the time. Frankly, I would not consider any of those noname imports for my house or bus. If I were to go tankless it would be Bosch, Rheem, Noritz (the one I have) or Rinnai. Also, if it is not AGA and UL approved, I would not consider it. | ||

I heard that tankless units are rated in degrees that the water temp is increased as the water flows through the unit. Since most residential water comes out of pipes buried in the ground, the water is usually around 65-70 degrees when entering the unit. A 35 degree increase would give you 100-105 shower water. In an RV camped in a cold area without bay heat could easily put 40-45 degree water into the unit, add 35 degrees and you have 75-80 degree water. I do not like cold showers! I would suggest checking the rating and see what the rated temperature increase is and consider the coldest expected water temp entering the unit based on where and how you use your unit.
