Has anyone heard of GlowCore?


I own an old Victorian townhouse in New York City. I know that the gentleman who restored my house starting about 25 years ago converted from an oil-burning boiler to a gas burning burner. He had also installed 3 whirlpool baths.

But 4 years ago (a year before we bought the house), the then owner replaced the boiler with a Laars Endurance EBP series which provides gas on-demand hot water for both domestic use and also our hydronic heat.

The problem is that next to it are two huge water tanks. They are electric powered. The plastic is split and coming off, and all I see is the word GlowCore. (Glow is in red, and Core in blue - or vice versa). I can't find any info online. I called the company that bought GlowCore (now based in Dallas, TX) and they don't know anything about them.

I think that these two heaters are costing me a fortune - (a) because they are old and (b) because the outer jacket is coming off.

Does anyone know of GlowCore and can they provide me any info?

Thanks in advance.

Are these two tanks connected to the plumbing in the house?

Since you have a low mass hot water furnace, I bet they are just storage tanks for the domestic hot water. If there is any "electric" hooked to them, I'm betting it's for a recycle circulator or a thermostat. We're just guessing without pictures. Post some, por favor.

Thats exactly what they are. When ever you have a hotwater boiler which makes heat and water for domestic use there will be a storage tank located next to boiler which looks like a water heater. I can't figure out why there is two. There is usually only one. Unless they figured you would need two for your domestic consumption. Big up on the east coast like in the Boston Area.

Sounds like they are storage tanks for the domestic hot water.

With 3 whirlpools taht may expalin why two are there instead of only one.

If they ae natural gas then there should be a vent to a chimney or outside.

The wire may tell the boiler when to heat the water up in the heat exchanger for each tank. Acts like a thermostat in a room to tell when the heat to come on in that room.

Is the wire of a smaller nature that goes to the tank?

I too have a crappy glo core system. It worked fine all winter and as spring warmed up in Michigan, hot water seemed to work fine. Now that we're getting a hard freeze tonight, the system is cold. Does anyone have any ideas for restarting the system? The pilot appears to be electric and we haven't had any power outages. Would flipping the system on and off do anything?

I know everything about GlowCore boilers.

These are indirect fired water heaters. The best way to make hot water available.

They were made for GlowCore by Heat Transfer Products, of stainless steel with a finned cupernickel heat exchanger. If you have soft water the insides probably look new though the jackets leave something to be desired.

The insulation is quite good.

A professional should be servicing your boiler on an annual basis and assessing the performance of these tanks and the boiler that drives them.

They are "powered" by the boiler and are not electric.

High efficiency condensing boilers are not a DIY project; this is especially true of the GlowCore boiler. Those who still have them in service should make a friend in the industry and plan on a replacement using the new and wonderful ModCon boilers, available everywhere.

Failure to read, understand and follow this simple advice could lead to serious personal injury or death.

Seriously.
