Munchkin Setup New Construction Advice

Dunwell

Hi all,

New construction in the Berkshires (NY/MA) area. Made contact with a very open and cooperative plumber who will work on time basis only. I'm homeowner, supplying all materials. He makes helpful suggestions and we work to keep within budget.

He did heat loss calcs (78k) and I'm about to make a purchase of boiler, water heater, pool heater. House will be well-insulated, radiant heating throughout (slab in basement, lightweight concrete on upper floors), with two adults only.

Please let me know what you think of this setup before I order:

*Munchkin T-80 (or 140 if suggested)

*SuperStor Ultra (SSU30) water heater

*Jass LT water to water heat exchanger OR SuperStor Pool heater (this is for an indoor lap pool, 7k gals. in a room insulated with Icynene). I'm leaning towards the Jass because of it's nice price ($300) and compact size.

I don't want to oversize the boiler, that's why I'm considering the 80M Munchkin over the 140M.

Want to keep this as simple as possible, but want the best efficiency (of course). What are the best controls to get? Would like outdoor reset and I definitely want hot water FAST.

Thanks for your advice!

Sounds like

you got it.

PLEASE, PLEASE, PLEASE make sure the plumber knows how to install and set-up the Munchkin!!!!!!!

This isn't the average, run-of-the-mill boiler.

You HAVE to size evrything according to the instructions, and you HAVE to set the burner up with a digital combustion analyzer. CO numbers are critical as is gas pressure.

The T-80 kicks butt!

Good luck and congratulations on your new home!

Thanks Mark...

...I wrote down the phone number for the Munchkin reps (Jeff, Sham, etc.). I'm going to hand it directly to the plumber and I know he'll utilize it because he's not a "know it all" type and actually DOES read instructions.
What are your thoughts on controls? I'm considering the Tekmar 260.

well


it would be nice if you could get the Vision package, but since neither of you are certified, that is not an option.

The Vision 2 package would handle your entire system.

The 260 is the next best thing.

HTP (Munchkin) makes a control package (the Vision 1) for the Munchkin that should do everything you need. Your contractor must be certified to purchase however. If you start trying to use other control systems you might get into problems--watch out!
