Here is the old boiler being disconnected. This boiler was probably installed in the 1970's and was working fine. It's efficiency rating was also probably in the 70's.![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgfO6KhyphenhyphenjknOWx1CBR17H3DREf_3aykeOxS7Lp7-U2IFcRelrddlIUCpH82f5CbkU-yv7394iCabxB1VWOJBtC9d5nzY6dj1qe7iS4Pjr7benzAsRsffjVrXdlySI_Ig_LKGnXS-kZGt8xW/s320/boiler_before.jpg)

Here is the new boiler installed and tested. It is a lot more complicated and has an efficiency rating of 93. It vents to the outdoors (one of those white pvc pipes) and has a temperature sensor outside the house so that it knows how hard to work.![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiFcHLZuiQTgxIC2DPdEsDpYIyreaOM86pYCTQXGA9K4z7JOdhNVFKIcUePk3p9uPw0SePn-AUYpl4XUVFpYfc45QJ8Tul1D3ocklglB84XEd3dIqsI-mNvAkinhVG2faE2WWyClbUj5uje/s320/boiler_after.jpg)

The air-conditioning system is called a mini-split. There are two units indoors (pic below) and this unit outside which is actually a heat pump so can provide cooling or heating or simply dehumidifying. One great side benefit is the electrician installed an outside electrical outlet..which I've wanted since forever.![](https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgymWEYIc-A_8dYn_ca1kneEJBMV9jQ8H8R8W_dWx5fyqB6TLMsDwWRk9Bmmo8Wy1NOobpSDA0k__MHmN4mT7ueynTNsF5kkoFNySqO4JascnM4iVm4wCDdiqVgzdKG-yWzDj-n35JWEjsp/s320/ac_outside.jpg)
