Hot Water Recirculating System
Summary: A hot water recirculating system will give you instant hot water - no
waiting. But installing them is easier in some homes than in others.
Hot water recirculating systems give you instant gratification -
steaming hot water at the fixture.

Steaming hot water as soon as you turn on a shower valve is a great feeling on a cold morning. The same is true at your kitchen sink or any other plumbing fixture. As our lives become more fast paced, we don't want to wait for anything. Instant gratification is unfortunately becoming the norm.
The installation of a hot water recirculating loop system will allow you to have hot water at your fixtures. Those people who have their heaters below the piping system get the recirculating work done for free Those who live in slab houses or who have hot water lines below the heater must use inexpensive in-line recirculating pumps. The point is that you do not have to wait for hot water.
New Construction vs. Existing
If you are building a new home or rehabilitating one, now is the time to put in a recirculating loop! You will have no trouble installing the return loop lines and insulating all of the necessary pipes.
If your house is an existing two story house, it can be tough to get a return loop pipe up close to the second floor or higher bathrooms.
It is also virtually impossible to properly insulate all of the hot water supply pipes.
Existing ranch style houses that have a great majority of the plumbing pipes exposed in the basement are the best candidates for retrofitting. These houses allow you to insulate all but just a few feet of hot water supply lines. They also permit you to install a return loop close to each hot water fixture.

This article indicates a slab home requires a system with a pump. The Hot
Water Lobster System (pumpless)web site doesn't say anything about not
being applicable to a slab home. Who is correct?

Don,
I don't make claims for products. You need to contact the lobster people and ask them about their limitations.

I contacted Lobster and they say the system will function properly in a
slab home.

The HWL didn't work in our home. Lobster said it was because we had check
valves in our water system or hot water heater (no according to AOSmith)
which I could never substantiate. Now I'm reluctant to try anything
including those that have a pump. Tony, you've endorsed it, but is this on
HWL's theory or do you have one in your home?
