Weil Mclain GV90plus 91% efficient cast iron boiler
*OUR #1 CHOICE IN HIGH EFFICIENCY BOILERS PAIRED WITH A SUPERSTOR INDIRECT HOT WATER HEATER*

 

PROS:

NO MAINTENANCE - With the exception of emptying a small drain trap, this boiler requires NO MAINTENANCE unlike a Lochinvar Knight, Burnham Alpine or Buderus GB142.

CAST IRON CONSTRUCTION - It is Mathews Brothers Plumbing & HVAC belief that cast iron will stand the test of time. Every boiler we replace is cast iron and is 30 plus years old.

$1000 GASNETWORKS REBATE AND IS ELIGIBLE FOR The 0% INTEREST MASSSAVE HEAT LOAN

 

CONS:

OTHER MOD-COM BOILERS RECEIVE A $1500 REBATE - This boiler is on average $500 less expensive than 95% efficient boilers, so it the final cost should be the same in the end.

91% VERSUS 95% EFFICIENCY - A high efficiency boiler usually runs between 89-92 percent efficiency. You will only achieve 95% efficiency if you are supplying radiant floor heating that runs around 125-130 degrees.

Lochinvar Knight 95% efficient stainless steel high efficiency boiler
*OUR #1 CHOICE IN STAINLESS STEEL HIGH EFFICIENCY BOILERS PAIRED WITH A SUPERSTOR INDIRECT HOT WATER HEATER*

 

PROS:

LARGE HEAT EXCHANGER - Stainless steel high efficiency boiler do not have large heat exhangers. The Lochinvar Knight has one of the largest compared to other stainless steel high efficiency boilers. Heating systems with large radiators and pipes can have a tremendous amount of dirt in the system. Small heat exchangers can become clogged where the efficiency in the boiler can decrease over time. The larger the heat exchanger the more room there is for dirt not to clog any of the passages.

OUTDOOR RESET - The Lochinvar comes with an outdoor reset. A outdoor reset matches the outdoor temperature to the boiler temperature. If it is 0 degrees, then the boiler will run at 180-190 degrees. If it is 45 degrees, then the boiler will run at 140-150 degrees. This all depends on what the parameters are set to, but to put it simply you will use less gas running at 140 degrees on a 45 degree day while still keeping your home between 68 and 70 degrees.

WALL HUNG DESIGN - This type of design save space and gets the boiler off the ground in basements that may have flooded in the past.

CONS:

YEARLY MAINTENANCE IS REQUIRED - The heat exhanger needs to be cleaned to maintain peak efficiency. Mathews Brothers Plumbing & HVAC offers yearly maintenance programs. Even if we did not install your heating system please feel free to call or email us to get a copy of our maintenance program.

SLOW TEMPERATURE CLIMB - If you want to lower your heat during the day to 62 degrees and keep it at 68 degrees during the evening, it will take more than 1 hour to achieve this as your boiler is operating at a low temperature. 3 degrees would be the maximum that Mathews Brothers Plumbing & HVAC suggests to lower your thermostat to.

LONGEVITY VERSUS CAST IRON BOILERS - There are cast iron boilers that are still in operation that are over 35 years old. This is why we prefer the Weil Mclain GV90plus boiler as cast iron has proven to "wistand the test of time." Stainless steel high efficiency boilers may last 25 plus years, but the technology is too young to make this claim.

Superstor Photo

Superstor indirect hot water heater comes in 45, 60 and 80 gallons
*OUR #1 CHOICE IN WATER HEATERS*

 

PROS:

NO MECHANICAL PARTS - The water heater is heated by the boiler, so unlike standard water tanks and tankless water heaters there are no gas valves, safety switches, venting or any other thing that could break or fail. There is no maintenance required and there is very little mechanically that can fail.

STAINLESS STEEL DESIGN - The tank jacket is stainless steel so Mathews Brothers Plumbing & HVAC believes that this tank will last 20 years. The idea is that you can match the tank with a boiler where the life spans of each are roughly the same.

$400 GASNETWORKS REBATE AND ELIGIBLE FOR MASSSAVE 0% INTEREST LOAN

 

CONS:

A BOILER IS REQUIRED - If you have forced hot air in your home via a furnace than you cannot have a Superstor unless you install a boiler. This is not cost effective.

SUPERSTORS ARE MORE MONEY TO INSTALL THAN JUST REPLACING YOUR CURRENT NATURAL DRAFT WATER HEATER - It will cost you more to change to a Superstor, but the life of your Superstor should be twice that of a water heater.

Navien Combination Heat & Hot Water Boilers

 

PROS:

HEAT AND HOT WATER ARE IN ONE SINGLE UNIT- The boiler provides heat and hot water. It is a 120K BTU unit that provides 4.3 gallons per minute in ideal conditions

NAVIEN IS LESS THAN MOST HIGH EFFICIENCY BOILERS - A typical high efficiency boiler is $3000 plus, but the Navien is a little over $2000.

ENDLESS HOT WATER - The Navien can provide endless hot water to a home with 1 shower running. At 4.3 gallons per minute, 2 showers would be difficult

$1600 GASNETWORKS REBATE AND IS ELIGIBLE FOR 0% INTEREST MASSSAVE HEAT LOAN

 

CONS:

NOT BUILT WITH THE SAME QUALITY AS MOST HIGH EFFICIENCY BOILERS - There is a reason for the price difference between a Navien and for example a Lochinvar. Quite simply the other two boilers above are high quality boilers that do cost more money. BUYER BEWARE IF YOUR CONTRACTOR IS ATTEMPTING TO CONVINCE YOU THAT THE NAVIEN COMBINATION BOILER IS THE SAME QUALITY AS A LOCHINVAR KNIGHT, BUDERUS GB142, BURNHAM ALPINE OR WEIL MCLAIN GV-90PLUS.

4.3 GALLONS PER MINUTE WILL NOT BE ENOUGH TO RUN 2 SHOWERS DURING THE WINTER - Ground water is very cold in the winter so you boiler will not produce 4.3 gallons per minute. It will be difficult to run a shower with a dishwasher and a sink running

YOU WILL USE MORE WATER - A water heater has water stored, where a tankless system has to produce the hot water. Therefore it will take longer for the hot water to get to your shower head or faucet as the boiler needs to heat up the water before it arrives at the fixture. Water rates are expensive, so any savings in fuel costs could be eliminated by higher water costs
