    Restore

    My local restore over prices most items and super over prices anything they perceive as collectable. It wasn't always like that, but changed when they hired a new manager. I finally got tired of seeing that and told them that I would no longer shop there and why. It's unfortunate because the...

    How long can you (and your family) survive if the grid went down for an extended period?

    Yea no your pipes would never fill up, BUT your neighbors at the bottom of the mountain will have their houses filled up with excrement from everybody living above them. That shit rolling down hill will find the path of least resistance and that will usually be someone else's toilets and drains.

    400 amp main panel recommendations? (Norcal, PG&E)

    My house was built with 2 x 200 amp panels and has worked very well for me when I decided to add solar. I shifted everything I needed that my modest solar system could handle to one panel and the other panel remains connected to the grid. The cost of installing enough solar to cover my whole...

    solar pergola on pavement, only weighted down

    There's one thing that may or may not be an issue and that is the possibility of the bricks sinking slightly into the asphalt. That is assuming when you say pavement it's made out of asphalt. I bring this up because asphalt does soften when heated so depending how warm it gets there and the...

    DIY Solar Water Heater

    I don't know if I should be inserting Amazon links on here but a simple Google search yielded an Amazon hit right at the top of the list. I just want to say that I understand the need to do as much as you can to save money, but if's there's anyway you can get a commercially made water heater...

    DIY Solar Water Heater

    Here in the states water heater thermostats are readily available and are simply held against the bare steel of the tank. The one for a single element water heater should work for your application. It's likely the same thermostat as the lower one on a dual element water heater and the...

    DIY Solar Water Heater

    I personally wouldn't do it because her in the states there's no need to plus it just adds more potential failure and safety issues. Are there no commercially available hot water heaters in the Philippines?

    DIY Solar Water Heater

    Actually I had forgotten about the solar water that I built about 25 tears ago. In this case I took a an electric water heater removed the insulation, painted it black and put it in wooden box with a glass top and pointed it towards the sun. I worked pretty good but didn't hold the heat very...

    DIY Solar Water Heater

    If your pump is going to be exposed to hot water it needs to be designed to tolerate the heat. When I was seriously considering installing a solar electric system I kicked around many ideas for heating water. But in the end I decided to scale up my system design to include using my standard...

    DIY Solar Water Heater

    I built a solar water heater for my swimming pool like that with irrigation pipes and it failed the first time water wasn't flowing through it when the sun was on it. The water boiled out and the pipe slightly melted. I didn't watch the video so I'm not sure if he used different pipe. I also...

    LG combo washer/dryer with heat pump/ventless -$2k.

    I wouldn't build or buy a heat pump dryer. I also wouldn't buy any new major appliances or vehicles for that matter. Every manufacturer in recent years has lowered their product quality and customer service. Add that on top of the complexity of the modern offerings of today and we often times...

    As a recently retired appliance repair man I wouldn't trust any brand.

    Any Growat SPF 3000TL LVM-24P Split-phase users?

    I've been running a pair of Growatt LVM 24ps in split phase for almost 3 years now. I had a problem with them within the first 5 weeks that was related to poor quality control. I was sent 2 new main boards under the warranty which took care of that problem. They aren't perfect and have a couple...
