Viessmann
Gas Boilers

Is it initial cost, energy savings, reliability, durability or impact on the environment?

Do you like the idea of high tech?

Gas boiler efficiencies start at the 83% AFUE (Annual Fuel Utilization Efficiency) and top off at approximately 95%.

Gas boilers that are rated above 90% are called condensing boilers.

The higher efficiencies are the result of utilizing the waste heat in the vent system that is usually lost to the atmosphere.

This type of boiler is never vented into a chimney.

It is vented through either a stainless steel or plastic pipe product.

The only brand of boiler my company sells are Viessmann gas boilers , a German manufacturer.

It is the only company that I felt comfortable with that could back the benefits that my client’s look for.

Arguably the best gas boiler that is available today is the Viessmann Vitodens 95.2% efficient wall-hung boiler.

Some are experiencing 50% reductions in their heating bills.

Besides being highly efficient, it’s one of the most environmentally-friendly gas boilers on the market.

The emissions from the vent system are extremely low (carbon monoxide = 5.5 ppm, NOx = 8.9 ppm).

The burner adjusts it’s firing rate to match the amount of heat that is needed.

For instance, if the boiler has a rating of 91,000 BTU’s of heat, the burner will only deliver 25,000 BTUs of heat if that’s all that is needed.

A conventional boiler would deliver the full 91,000 BTU’s regardless of the amount of heat needed. It’s like stepping on the gas pedal of your car, then slamming on the brakes even though you were only going one city block.

This modulating burner strategy saves fuel as well as wear and tear on the boiler.

One feature that I like is the burner is a flameless, radiant heat source.

Another energy-saving feature is the control system also adjusts the water temperature according to the outdoor temperature as well as the indoor temperature.

This is very important when using a condensing boiler.

These types of boilers rely on lower water temperatures to gain maximum efficiency.

Stay clear of those who try to sell a condensing boiler without this control strategy.

I’ve seen high efficient rated condensing boilers that were operating at efficiencies in the 80% range because the water temperatures were too high to allow the boiler to condense and release the extra heat into the heating system.

The Vitodens is also made from one of the highest grades of stainless steel.

It’s also very quiet. I’ve had to put my ear to the cabinet to be sure it was running.

Viessmann also makes a 83% efficient model.

This is considered their basic model.

Though it doesn’t have the bells and whistles of their advanced model, this Viessmann boiler still has high quality German engineering.

Prices can range from $13,000 down to $5,000 for these products or comparable ones,, depending on the size and scope of work.

I don’t have time to research every gas boiler on the market.

The next best thing I can do is when I’m introduced to another boiler manufacturer I use Viessmann standards to compare.

So far I haven’t found anything that can stand up to the quality.

If you are in the market for a gas boiler you can make the same comparisons.
