A few weeks ago, we started work on Mario and Kathleen’s mountain home near Nederland Colorado.

When we started work, they had only one source of heat- a large wood-burning stove in the basement. Needless to say, there were a few hot and cold spots in the house. Coldest was the bedroom, and hottest was the basement. Everywhere else in the house was “tolerable”, except for first thing in the morning, when it was downright polar!


We installed an NTI high-efficency boiler and ran pex tubing (cross-liked polyethylene) to all the rooms, where we installed Beacon-Morris fancoil unit heaters. Each of these heaters was on a circuit with thermostats in different parts of the house- a true “zoned heating system”. The comfort from each of these fancoils is tremendous- and they are quiet units. The fans come on and go off as the hot water circulates through them when each of the zones calls for heat. We also installed a radiant floor system in the upstairs bathroom below the tile. It’s about the most pleasant place you would ever want to take a shower. There is also a snowmelt system coming off the same boiler that heats the walkway going out to the hot tub, so nobody has to freeze their feet going to take a tub.
The whole system was installed in less than a month, for a fraction of the cost of what a ducted heating system would have cost. It’s been in the teens at night lately. Not inside. 70 wherever they need it to be. And rooms that aren’t used are kept cooler for efficiency.

Needless to say, Mario and Kathleen have joined the 21st century, and are loving the transformation of comfort. A little secret, though. They still burn “a little” wood. Mostly for the ambiance and the smell of a mountain wood fire.

Why Risk Coming Home to a Flood? Tankless Provides Protection…

Consider the real issue of what happens when your water tank decides to give up the ghost. It happens often without warning. For the lucky ones, a couple drips under the tank are noticed and it’s “time”. In the other 50% (yep, half!) of the cases, the bottom drops out or the side splits from a faulty relief valve and the basement becomes a swimming pool, or the crawlspace a swamp. Or the condo below fills up with water. Or the main level becomes an ice skating rink, or… you get the picture. Perhaps you have been in this situation. It’s not pretty. Tankless systems don’t hold water, so no danger of flood!

Eternal Water Heater Failure

eternal Eternallogo


Many homeowners have had problems with their #eternal #tankless #water #heaters. Since Grand Hall company was dissolved, these units have left customers high and not-so-dry. Having installed several of these units, we are experienced in replacing these discontinued water heaters with the more reliable units such as #Rinnai and #Navien. We can usually solve the problem within a few days, and same day service is often available for emergency situations. If the unit can be repaired, we carry most of the parts needed.

Salon owner increases energy efficiency and creates unlimited hot water


Patrice von Metzger is a salon owner in Longmont, Colorado and employs several aestheticians, hair stylists, nail technicians and massage therapists. Patrice has a thriving business and is the go-to spa for many Longmont residents seeking health, beauty and relaxation. The Sunflower facility is state-of-the art, and has many nail and hair stations, a body wash and an in-house laundry facility.


Having adequate hot water is critical to any spa. From washing hair to washing towels, without hot water, everything comes to a screeching halt. And that is exactly what happened on December 23, 2017. Patrice came into the shop to find the 120-gallon 300,000 BTU water tank had sprung a leak. She was facing having to replace it with like in kind and likely face the same problem in another 7 years, which is the amount of time the tank lasted. Not the kind of problem a business owner wants to face, especially with Christmas season right around the corner.


After considerable research, Patrice found that the cost to replace the faulty water heater was over $8000, so she set about looking for someone to advise her. She was referred to us by one of her colleagues, and we proposed a Navien NPE-A series tankless water heater with an 80 gallon storage tank for under $6000. Problem solved! The salon is now enjoying more hot water than they need at a considerable savings in energy costs over what they were paying with their big, leaking monster. In fact, we were able to remove the additional 50 gallon water heater that was serving her adjacent hair salon, and combine the two systems into one efficient, compact system.
