Save money and energy by upgrading the boilerin your Seattle area home.Boiler Replacement

If the boiler in your home is 20 years old or older, you can save a substantial amount of money and energy by updating it.  Older models of boilers can have efficiencies ranging anywhere from 55% to 70%.

That means 30 to 45 cents of every dollar you spend heating your Seattle area home is being wasted.  That’s a lot! 

Here at Carlson Mechanical, we don’t like to see homeowners throw their hard earned money away when there’s a simple solution-replacing your aging boiler.

There’s been many technological advancements since your home’s boiler was installed and you can greatly benefit by upgrading to a high efficiency model.

Why replace your boiler?

  • Save money and energy
  • Improved safety features
  • Reduce chance of breakdowns
  • Increase comfort level in home

How does 95% efficiency sound?Lochnivar Knight Boiler

Our most popular boiler (the Knight from Lochinvar) has earned the Energy Star label with a 95% efficiency rating, which can reach up to 99% efficiency if you have radiant floor heating in your home.

Now, you don’t need to be a math genius to see that you’d be saving a lot of money and energy by replacing your aging boiler. Many of our current customers who updated their radiant heat systems saved even more money than they expected.

Just wanted you to know the new heating system came through the cold weather with flying colors! The house has never been so comfortable in all the years we've lived here----it's a HUGE difference. We just received our first gas bill and had about 25% less gas use than the same period last year.

Lochinvar Knight high efficiency boiler

Just like a knight in a fairy tale, the Knight boiler from Lochinvar will save you from high heating bills this winter while doing its part to protect the environment.  Rated at 95% efficiency, it can reach up to 99% efficiency when used in radiant floor heating systems and you can’t get much better than that!

With low NOx emissions (less than 20 ppm), you can feel good that it’s doing its part to make our environment better.  It’s the best green choice for your home.

SMART SYSTEM sets it above the restLochnivar Boiler SMART SYSTEM

All 7 models of Lochinvar Knight boilers have the SMART SYSTEM, the most technologically advanced boiler control on the market.  Its large LCD screen with easy to use soft keys gives the user access to a complete database of performance history and ultimate control over all the system functions in 1 place.

A color coded screen lets you see its status in a glance. A blue screen lets you know it’s functioning as normal while a yellow screen tells you when it needs regular maintenance (in case you forget).  It even displays the name and number of who installed it-how’s that for convenient? A red screen alerts you that it’s in lockout mode and needs immediate attention.

Boiler Upgrade

Superior design = energy saving features

The space saving wall-mounted Knight boiler has many features that makes it one of the most efficient boilers on the market today.

Outdoor Air Reset

The outdoor air reset feature automatically adjusts boiler supply temp based on the temperature outside.

Why is this a big deal?  This feature overrides the manufacturer’s settings for the “worst case scenario” design temp of the heating system. 

This saves energy (and money) because our weather in the Pacific Northwest is often not as cold as that “worst case scenario” temp so there is no need for the boiler to work extra hard when it’s not necessary.

Fire tube design

The ASME Certified stainless steel heat exchanger has oval-shaped tubes to pass heat to the water stored in the vessel.

To further aid the heat transfer, the tubes have dimples to slow the flue products and help extract any available latent energy. 

Water-back combustion chamber

One of the amazing features is the fire tube design with its water backed combustion chamber.  While this might not mean much to the average homeowner, it’s one of the reasons that it’s so efficient.

Since the combustion chamber is surrounded by water, there’s more heating surface area and that larger area allows for efficiencies up to 99%.

Fully modulating burner

The SMART SYSTEM permits fully modulating combustion with a 5:1 turndown so the burner can fire as low as 20% of maximum input and ramp up to 100% as demand increases.

The burner fires in a 360-degree pattern along the entire length of the burner so the Knight boiler can surpass the capabilities of other boilers with larger multiple burners.
