Two-story Victorian desperately needs a cost-efficient radiant floor heating source
Greetings from Cleveland, Ohio, USA
I have been lurking her for a long time, finally, frustrated and running out of time ahead of the heating season I seek your help.
Thank you for allowing to share my heavy burden,
Back story: I was sold a house by a nefarious neighborhood development corporation nonprofit who is now over their heads with indictments and investigations by local and federal authorities. Long story short is that I was forced to rebuild a house or lose it. Originally, I bought this house with new paint, carpets, furnace, fixtures, and then basically was forced to rip everything out and rebuild it. With the new relevations steming from the courts — all this was done in the hopes that I would give up on the house. They did it over and over to many people. I learned everything as I went forward with the project. From digging out and pouring a new foundation to sistering just about every joist. I decided that I may as well just get the house down to studs and rebuild it my way. The last five years of my life have been dedicated to doing just this — making me poorer, smarter, and meeting some amazing people who helped me along the way — some of which decided to stick around as my good friends.
The house: Circa 19teens crayon-box two story house down to studs with original 2×4 balloon construction furred out by 2×6 on 3 of 4 walls of the house. Ceilings are 10′ & 11′. Floors are 50/50 divided in a 1.5″ thick glued and screwed sandwich of the original 100 year old oak t&g and plywood (for a later hardwood install) and for the future tiled areas the flooring sandwich consists of two glued and screwed 3/4″ plywood sheets and Bekotec-like panels+pex+screed sandwich.
My mechanicals are in back the second floor walk-in closet. Manual J calculations are asking for 100k heat, 12.5k latent, 50k cooling, 36.5k sensible. I have 6 loops of ~200′ of 1/2 O2 barrier pex per floor. The system is divided 50/50 between a 4-run-per-bay staple-up backed up all the way by omega shaped channel aluminum panels and Schluter Bekotec-type product for tiled areas.
The problem: For the last two months I have been attempting to ascertain which heat source should be driving my radiant heat flooring installation. I have been running from one boiler manufacturer to another and after reading user reviews and running back to hot water tank-type installation. More information I read on the topic and more reviews I read about my options the more scared I become to pull a trigger.
Recently my finances have taken a very dictatorial tone, unallowing me the means of retaining a qualified professional, and due to the aforementioned fears and frustrations — I am just thinking of throwing everything I learned on the topic out of the window, and temporarily throwing a cheap Rheem NG tank in a closed loop with an expansion tank, air eliminator, ‘smart’ circ, and a few valves and calling it a day; on better days I think of buying a HTC Light Duty.
Here is what Ohio Laws say about using a water heater for heating. I am actually not 100% sure that I understand the law completely, but I think I can use a hot water tank to heat my house witout also using it as a domestic hot water source http://codes.ohio.gov/oac/4101%3A3-5
