These heaters are worth the extra cost over conventional heaters
Water. The heaters arrived quickly and in good condition. They work as advertized, giving silent heat without high surface temperatures. I recommend them to anyone contemplating electric baseboard heaters.

Product and Air-N-Water top notch!!
As a contractor, I use the product very often as it is superior all around. I have used many suppliers and find that Air-N-Water is better than even those that I thought to be the best. Way to go Air-N-Water!!!!! Best prices, quick delivery and fantastic website for online ordering.

The family of hydronic baseboard heaters are tough to beat. Efficient, affordable, easy to install with simplicity of design. I've bought three so far, and after doing my web research, purchasing, installing and using these units, I really don't think there's a better product on the market for price/performance.

I purchased this product because I added an additional hydronic baseboard heater to a project I completed earlier this year. I used the same brand and type of heater because I liked what I bought from you on my original order. It has performed excellently! We installed a fairly large solar electric system this past December. Part of the conversion is over to using solar/electric heat instead of our gas heating system. I also really like hydronic heaters versus the less expensive baseboard heaters. It provides silent, even heating. I would recommend this to others.

Question:
Why did you buy this item?
Answer:
Bought this heater from Air & Water last year for upstairs bath. Very good quality heater, price is reasonable, shipping was quick and heater was packaged well. Am buying this same heater for downstairs bath now.
- Aldon R. on 04-25-2014
Answer:
I have Hydro-Sil heaters throughout the house. The company went belly up and the comparable option is hydro-comfort. Since my lifetime warranty is basically trash, I can no longer justify the additional $100+ for the hydro-comfort unit. Since the Q-Mark unit looks similar to the Hydro-Sil unit, this is looks to be comparable in operational costs and will likely replace future failed Hydro-Sil units.
- Jim D. on 05-24-2014

Question:
If I have a old baseboard heater 220V in place now with a thermostat on the wall will I need to replace the thermostat if I get these type heaters. HBB504 Model? Fred
- FRED G. on 02-20-2014
Answer:
As long as the wattage and the amperage for the new heater is below the maximum allowed for the thermostat then you can still use the same thermostat.

do these units require extra electrical work or are they ready to plug in?
- Anonymous on 02-09-2015
Answer:
They do not just plug in. This model runs on 240 Volt and works best a dedicated circuit .
- Paul B. on 02-11-2015
Answer:
The one I purchased in 220 volt and it does not plug in. The 110 one might not come with a plug either. They are hard wired.
- Paul M. on 02-10-2015

the ones I ordered are hard-wired
