Hey everyone, got a few questions on baseboard, looks like I’m not doin the in joist heat, it’s just way to much money, so I’m now looking at baseboard as it’s about 1/5 the cost, and is Still going to be a huge improvement from the current forced hot air system..

Do I do one zone, or multiple? Obviously with multiple I get more control and comfort, so can you have too small of a loop in a zone? Obviously you can have to much baseboard, but can you have too little? Upstairs is a two bed two bath, so I’m planning each bed and bath be on it’s own zone, looking at 14’ of baseboard for each, no big deal?

In total I will have 3 zones, one for sons bed/bath, one for daughters bed/bath, and one for kitchen living room, with 3 thermostats.

Comments/concerns anyone?

Given a choice would you keep your bathrooms and bedrooms at the same temperature? Most people prefer a warm bathroom and a cool bedroom.

I could just split them into more zones, would have 5 then, 5 thermostats and 5 zone valves, I just figured I’d put them on the same zone because there connected to the rooms.

I don’t believe a zone can be too small. To big…yes! Too much heat loss on long runs.

Especially if I split it up into zones, my longest run will be 24’ of baseboard.

A compromise is to group rooms into zones based on the desired temperature.

E.G. bathrooms, bedrooms, and living areas on 3 different zones.

Small zones are to be avoided with modern low mass boilers. Since you aren’t in that club, don’t worry about the zone being too small.

24’ of 3/4” baseboard is no problem at all.

I attached a one page list of "rules" for you to keep in mind.

Oooops. I misunderstood this thread. I thought it was about baseboard/mopboards. I still haven't machined my up-stairs bedroom baseboards, after overhauling the room, about 10 yrs ago.
I guess you're discussing radiators. :oops:

Thank you for posting that. I see 3/4 inch is capable of 40,000 BTUs. This will help me with my hot tub project. I plan to run lines to heat it with the Axeman since I want to give the boiler a little more to do in the summer (other than just DHW).

Nope not discussing radiators, I already have some of them downstairs, I’m talking about baseboard heat upstairs.

Are you planning on using copper?

I’m pretty sure 3/4” is equivalent to a little more than 1/2” copper.

I just heard recently that a 10' length of 3/4 copper cost $30! :o

You are probably right. I had to buy one 10' length of 3/4" type M copper when I did my project in the fall and I questioned the cashier on the price. Thankfully I was able to do most of my heating system with reclaimed copper from the old system.

Did the decorating committee vote down the radiators? 8-)

If you are concerned about wall space take a look at high-output baseboard. It puts out roughly 50% more heat per foot and is only about an inch taller.
