New 2 gallon expansion tank factory set to 40psi and circulation pump

I just finished installing a new expansion tank (factory set at 40 psi) for my natural gas water heater. I use a Grundfos type UP 15-10 B5 circulation pump. Other markings on the pump label are: P/N 59896213 P1 and what looks like a mathematical formula: I 1/1(A) with the number .22 below it. And P1(W) with the number 25 below it. Do I need to change the pressure on the expansion tank? BTW my street water pressure is about 50psi. Thanks ..read more

I am looking at replacing existing water heaters and have run this by 3 different local plumbers and got 3 different answers. I know this is way more info than you need but each plumber had different reasons for why this and/or other options would not work. The house has 3 electric tank water heaters (2-50gal. & 1-40gal), with no gas availability. Water heaters are mounted in small separate closets (24"x30") with doors opening to outside of the house. House is single story and shaped like a... Read more ..read more

My hot water cylinder is leaking at the top from the immersion thermostat socket I will note that the immersion part is disconnected and the thermostat on the side is being used to heat the water by oil now. It's not a super fast leak but I need to fix it asap. Call a plumber? Unscrew and thread with plumbers tape etc Or get new but to put in the top? Those seem to be my options. Has anyone got any advice or tips to maybe buy some time before a potential whole new system that's modern... Read more ..read more

Replace existing 2006 hot water tank?

Hello Community, I am currently updating the equipment in a high-end residential mechanical room for a luxury residence and am evaluating whether it's wise to also replace a still-functional 120G hot water tank from 2006. The unit in question is a "Warnock Hersey Water Comfort" indirectly fired hot water tank, model J 120 DW/XL, manufactured by Advance Metalpres Inc. It is part of a hydronic heating system, so it is an indirect water heater tank. The water tank is heated by a Weil-McLain... Read more ..read more

Two water heater plumbing correct?

I just had two water heaters replaced. Same tanks and size but installer plumbed them differently. Was previously symmetrical (same distance on each side of the T joint to each water heater). The new plumbing is not symmetrical. Roughly 9” from T joint to left heater and 15” to right heater. Is this done incorrectly is there a reason to do it this way ..read more

Solution for steam Kickspace Heater.

So we are remodeling our kitchen and have a two pipe steam system, I live in an apartment building so I can't change that. We are very limited on space and would love to use a kickspace heater. A plumber I talked to said I should just hook it up to the hot water supply for my buildings potable water, but I worry I would be using a ton of potable water since I imagine it would have to go back down the drain, plus it will only reach about 120 degrees most of the time. My idea is what if... Read more ..read more

HTP phoenix light duty repair or something better?

So... My HTP light duty heat exchanger (NG) developed a leak. Took it apart and found the burner tube full of water. Cleaned it out and it slowly refilled. I was pretty happy with this unit and was using it for radiant heat in my basement floor and it seemed to do fine. So here's my weird idea... I found a 50 gallon HTP light duty but it's LP. It's 700 bucks brand new old overstock. Manufactured date was 2014. I'm thinking I could buy it and put all my old natural gas guts on it and have a... Read more ..read more

AO Smith Proline has great hot water in a.m. — very little in p.m.??

Hi everyone! Interested to hear your thoughts. In the early part of my day, I'm very happy with my AO Smith water heater — family of four, pretty much all of us can get a hot shower, maybe 40 or so minutes of hot water there. But at night? Completely different! I'd say there is 15 minutes tops of hot water, consistently. Can you think of any reason this would change over the course of the day???? Thanks for any thoughts ..read more

Weird things I found when fixing my water heater - please tell me this is okay

Hi all, I am new to this forum, so please let me know if I need to restructure this post. A few days ago my 17 year old water heater stopped working after the power tripped. The heater runs on gas so this was probably a coincidence – but I add it in case somebody thinks it’s relevant. After some time on Google and YouTube I decided that it’s probably the thermocouple that was dead (the pilot light would come on but die as soon as I tried to turn the system to normal function). I replaced... Read more ..read more

Water heater design oriented towards heat pumps
Terry Love » Water Heater Forum
by jg167

A heat pump water heater has a longer recharge time then gas or electric water heaters due to their lower heater capacity (likely not the proper term but the supply of heat). All the tank hot water heaters (i.e. not tankless) I am aware of follow the same design. Hot water is supplied as needed and as the level of the water is drawn down water from the line is used to keep the tank full which of course immediately cools the water in the tank down bringing the heating method online to...
