Hey Nick.

[chazwood]

I'm trying to fight the urge to resurrect a 120 day old post......(the red warning banner scared me )  so I just started a new one.

I noticed in your posts you talk about a Colman and Dometic Basement heat pump but I can't seem to locate specifics. Can you provide a dummy link for me?......(call me the missing link.)

Hi Chaz,

Basement heat pumps are an alternative to roof top and can give you a much quieter system.
Here is a start

Here are some pics of my units that are stacked useing 1/4 of my bay on the drivers side.

Total of 2 1/2 tons [30,000 btu's]  The second pic is after the installation of a Hydronic coil in the return
that is heated by a X45 Proheat diesel fired unit for redundant heat.

When I visit their web, all I see is the rooftop units. No pictures of basement units. I would like to see what is included in the package. ( this helps me understand whatall need to be done.)


Thanks

Hi Chaz,

I know, they have very little on the site.. That's because the installation of thees systems are not easy enough for the non HVAC consumer.

I have one on the shelf in the shop and I can take pictures and post them. If you look at the pics above, you can see where the supplies are.

[the two 6" flex ducts] They can either be ported from the side or the top. Then to your main trunk supply of your own configuration.

The return side is just behind the flexes where the hydronic coil and filters are. The return is ducted into my return tunnel of the coach and shares with OTR air.

The metal work behind the fire extinguisher is the hot condenser air discharge to under the coach. The smaller metal work front dead center is the condenser make-up

air, there is one on each side and that also picks up air from underneath in a different direction.

Hope this helps

Do you sell them?

[travelingfools]

Nick, How does the cost compare ?

[Nick Badame Refrig/ACC]

Hi Guy's,

They are a few dollars more then roof tops.

Advantages- super quiet operation, customizeable, no dripping from your roof, clean roof lines, no heat load from the sun,
                  ability to direct air where you want it, & more efficient then rooftops without the sun beating on them.


Disadvantages- takes up bay space, costa a few dollars more, added expence of materials & labor to construct ducting.

Good Luck-

Chaz,

I think Nick also sells Mini Splits.  Advantage there is "NO DUCTS".  That was a serious feature for me to consider.
