"Looking up"

So we got the Laars Mascot II about four years ago. Energy bills are great, especially compared to the 30 year old boiler we had prior to this. Having unlimited hot water is great with 6 kids. I did just have an issue where the heater stopped working. Had the company who installed it come out to take a look and was told I'd have to replace the control panel. After a phone call I was able to speak with the CEO of the company who ended up sending a serviceman out to look at my heater. It turned out that nothing was even wrong with it. I literally watched him clean the mixer valve and the hot water began to flow again. I am so appreciative of the great customer service I got from Laars and also from Peter of Ben Franklin Heating.

Have been waiting for a replacement part for 3 weeks. Shipping is disorganized, unreliable, and 'economical with the truth'.

I had a Mascot II installed a few winters ago and have been totally happy with it. It is super quiet, compact, and I have saved a ton of money by switching from oil to natural gas. I also was able to eliminate my domestic hot water tank because this unit has the integral DHW heater. I can fill up the tub and immediately run the dishwasher or laundry without having to worry about running out of hot water. I've been very happy with the installation.

Had it installed after Hurricane Sandy, having switched to gas heating. It hasn't worked correctly from day one. Please don't purchase one, not unless you want to wake up to a cold house and enjoy icy showers.

Had the Mascot II installed 2 years ago. From day 1, the heat has always worked okay, but the hot water cycles on-off-on-off every 4 minutes. Laars replaced the controller board and it worked fine for a year, just enough to have it be out of warranty, and then the same issue appeared. Now it cycles every 2 minutes. I called Laars but they are no help, they told me the unit is out of warranty and to find myself a plumber. Gee, thanks…
