I have built my new 2700 sq.ft. workshop with 10 loops on two zones in the 6"-8" concrete pad (lots of insulation on the edges and under the pad!) and now I'm looking for ways to heat it with propane for the next 3-5 heating seasons in Ontario Canada (cold!).
When the budget allows, it will be heated with geo-thermal as I am located on 20 acres with no hope of natural gas. So until then I will need a boiler of some sort with a low up front cost. (Not looking for as much efficiency right now, rather a good reliable, fairly low upfront cost system.) I've been doing a lot of research on boilers......floor mount, wall hung boilers and tankless water heaters and would really like as much advise or feed back as I can get with your opinions.
First off, what is the difference between a tankless water heater and a tankless boiler? (besides price).
2nd: whats the difference between a floor boiler and a wall hung, are they both tankless and/or instant?
I have learned that a tankless water heater can be dialed in for the lower temps. that are required for a radiant floor where as a boiler would need a mixing valve to regulate the temp.
I also have learned that tankless water heaters are not manufactured for the most part for heating applications and would/might void the warranty of the unit. Although a few manufacturers have made tankless water heaters that are specifically designed for recirculating applications. ex.Bosch GWH 450 ESR.
When I talked to their rep., they recommended it be used with an external tank which would put me back at the boiler price tag.
Any help on this is greatly appreciated.
