Greetings. I am a DIY guy who does everything himself. I am on to my next project which is replacing the old heating situation in my house. The house is in San Diego and is only 1800 sq ft. Half of the house I am keeping and the other half I am tearing down in a few years. I was planning on using radiant floor heating in the part that I am keeping, will be carpet, and some hydronic air handlers in the area to be ripped out later. My house is on a slab so I am looking at putting down Warmboard type product.
My questions.
What are the chances I could run a half and half system off of a dedicated on demand water heater?
How difficult is if for a DIY person to install everything?
What other options besides Warmboard are out there?
I don't mind the cost so much as the thinkness. I can;t really afford to lose that much height in my house. I have a smaple of of the Warmboard and it is very impressive. I am thinking that the quality of the Warmboard might allow for the on demand water heater as opposed to a boiler.
Do I need a lot of BTU's for an 1800 sq ft house with no insalation, leaky windos and Southern California weather?
Has anyone used the Hydronic Air Handlers? In combination with radiant heating?
Are there any books or websites that are must reads to get this right?
Has anyone used the warmlyyours.com electric mat?
Thanks for any input or suggestions.
I don't work for any of these people so I will list te places I have visited in my research. Am I missing any that are good?

First question... you're in san diego, and you need heat?
I have an uncle who is an architect in that area, and he keeps making fun of me because of the constant 70 degree year round climate there ;)
If that's even CLOSE to the situation you're looking at, I think you'd be wasting your money on radiant. It's be on so rarely, and would be so cool to run (or, would run so infrequently) that you pretty much wouldn't even know you had radiant heat 90% of the year.
That said, on demand water heaters aren't that great for radiant heating. You can make them work, but for what it takes, you might as well just use a tank water heater and turn it off in the summer. and fall. and spring. and most of the winter, in your case ;)
hehehe.. I just checked ASHRAE's weather data on your area. Your design temp will be 45 degrees.. I guess it can get chilly there once in awhile, but it sounds like it rarely gets below 50 or so?

Do we need heat in San Diego... well 90% of the days I would say no. The wife, like most wives is almost always cold so perhaps if anyone knows a cheap wofe available I could switch her out and skip the heating work.
We get a few months of 40-50's and have a baby on the way so I understand that babies like to be warm. We don't need a lot of heat but I am afraid with my leaky windows and lack of insulation that a forced air solution will be running constantly. The $5,000 for a forced air solution does not thril mean when I think that I could put that towards a radiant system.
What about the hydronic air handlers? I know they are blowing air around bt then at least I am buying a bioler that I can use for radiant at soe point rather then an air handeling system that is only good for blowing air. Besides as I said before I am a DIY guy and I don't see me doing all that sheetmetal work for ducting.
Is radiant just not the way to go for heat in San Diego?
Someone tell me about hydronic air handlers....
Thanks everyone for the input.

Frankly, for the kind of load you're looking at, I'd probably just put in electric baseboard and put the rest of the money into envelope upgrades (better windows, blow in some insulation). The windows/insulation will affect your comfort more than your particular heating system will (given it will be on so infrequently) and would reduce any cooling loads you have as well for a "double benefit".
If you did radiant floor, I would use floor sensors to maintain a 70 degree minimum temperature, so at least you won't have cold floors. They won't be roasty, but they won't be cold either.
