The Integrated Hot Water Domestic and Heating System is completed!

Old water heater for domestic use was gas-powered 50-gallon tank rented from Direct Energy for $14 a month. Not really efficient and, at a long-term, money burner. Partially driven by inability of Direct Energy to provide acceptable exchange options for loyal customers and future considerations of utilizing solar energy, we decided to go ahead with green replacement option.

The new, 79-gallon, indirect Wiesseman Vitocell-300 model with second radiator coil for using with optional solar power collector, was installed. This tank is connected to high efficiency boiler and has no gas consumption. Yes, this is the point – high efficiency boiler is only the source for hot water, both for heating or domestic use. Note, that new tank don’t need all those safety labels and warnings, as it designed to provide 100% quiet, safe and efficient operation.
The future is friendly – connect solar power water collectors to the second contour and you will have high efficient system that use boiler only as secondary source to heat the domestic water.

The diagram shows how the solar energy may be utilized for heating water for domestic use.

High Efficiency Upgrade – Part One : Boiler

Great green upgrade of heating system! May be, the one of the best for entire home.

Here is the full story. Having the water heating system in the house it’s apparently important to have efficient boiler. The old one was oil-based and despite the good working condition was decommissioned due to incredible “efficiency” to burn fuel and waist heat into exhaust pipe.

The new one is EnergyStar-rated, sleek and high performance, fully automated wall-hanging unit using natural gas. It has ability to manage two separate contours – one for radiant heated floor in basement and another one for main floor radiator-style. It’s computerized and has temperature sensors for not only supplied water, but also for return, incoming from outside and outdoor air.
Depending on weather, it supposed to adjust mode on the fly to make sure the heating is provided with maximum efficiency. It’s amazing, but exhaust pipe is made from plastic – it’s really cold because all of the heat of burned gas is utilized 93%!
The ultimate difference that unit doesn’t heat water as much as possible; it heats it just right to provide minimal difference between radiator and room temperature and get minimal gas consuming.

The info about unit – Triangle Tube Solo110, natural gas model, limited warranty for 10 years.
