I want to streamline my hot water system setup to hopefully save electricity and money. Let me first explain my hot water setup.

I have a Takagi Mobius TM-1 tankless water heater that receives cold water and outputs hot water on demand. The initial problem I had with water being on demand was I would have to let the shower run for 3 minutes just to get hot water. To remedy this, I had a 10 gallon electric heater hooked up to the hot outlet of the tankless water heater to maintain a reservoir of hot water that I would recirculate through the house every 30 minutes through the use of a recirculating pump.

The problem I have with this setup is my electrical bills have been really high and I'm sure the electric heater is not helping matters so I'm trying to find ways to lower that expense. I'm not sure how much I'll save but I think it may be as high as $50 per month.

The following pictures show the tankless heater and recirculating pump right after the electric heater was removed. The plan is to bypass the electric heater and go straight from the tankless water heater to the recirculating pump.

Since the system is open, I decided to flush the tankless water heater. You are supposed to do this every year but it has been two years since I installed it and haven't done it yet. We are using two bottles of white vinegar.

A small pump is connected to the cold water line entering the tankless water heater and a return line from the hot side is fed back into the bucket.

Here you can see the whole setup in action.

I still don't have any way to get into my garage and have been wondering about a fingerprint scanner mechanism so the kids won't have to remember a code. Well, I just found one that's made by Craftsman. According to info I have read, it can store up to four unique fingerprints and takes about a minute to program it. You can read more about it here.

What I like about it is that you can program a contractor's fingerprint into it for the one or two days he needs access without giving a numeric code. When he's done working, remove the fingerprint from the system and he's locked out!

I have a problem sleeping when it's light out. Now that summer is coming the sun is rising earlier and as a result I'm waking up now at around 5:30AM. Some of you may have noticed in looking at the pictures that there are no shades, blinds, or shutters anywhere to be seen. It's not that we don't want any but we need to get a specialist in here that works with Arts & Crafts style shades and figure out how to incorporate them into the house without covering up all of the great woodwork.

In the meantime, I wanted to share with all of you that I just purchased some eyeshades which are extremely comfortable, soft, and they block out 100% of light.

Last week the central vacuum would not turn off. It is a Modern Day Silent Master S5. I couldn't figure out what was wrong so I unplugged the unit. I called the installer, All Makes Vacuum and Sewing Machine Co., who I also purchased it from, to see what they could do. The owner, Carl Tice, came out yesterday and in two minutes he removed the vacuum and put it in his truck. He thinks something went wrong with the circuit board. Today he returned with a new circuit board already installed in the vacuum and put it up in 30 seconds. No questions asked, it works great, and I got great service!!!

The koi pond has been entered into a pond landscaping contest for the LA area during June 6th to June 8th. Due to its size, the pond was entered in the small category of under $10,000.

In preparation, Cor van Diepen of Paradise Landscaping, came over with his assistant Cesar (see April 16 blog post) for one last touch up before the judges come over this weekend. They spent time on details like making sure no rubber trim was showing and that every rock was in its place. There were a few bubbles showing at the waterfall that he called 'foam' and said we would lose some points if that was there when they came by. I'm going to see if I can find something to get rid of it tonight.

Cor thinks we have a really good shot at first place! I'll let you know next week. Maybe I'll get to stick a sign in my front yard. :)
