Greenhouse heating system repairs.

The first two of the new (we have had greenhouses since 1914 or so) greenhouses were built in 1984/5.  After 26 years, my headers on the hot water heat system is failing.  I have attempted temporary fixes for the past couple years, but this year I am replacing all the headers in the first two houses.

What is a header?  A header is a distribution point.  When hot water leaves the boiler and travels through 2.5 and 2 inch pipe under the benches, it goes up to the benches and is distributed through a header.  The header is one inch pipe and transfers the water to micro tubing.  The micro tubes are 1/4 inch in diameter.  We have over 50,000 feet of micro tubing.

Here a few pictures of a header being replaced.  The process is tedious.

This is an old header.  Last year, I attempted to glue the leaking  pieces.  It worked OK. but its time for new.

Header cut out.

New header partially re-atttached to the micro tubes.

new poinsettia updates.

Here are a few pictures of the 2011 poinsettia crop.  As you can see we are spacing them out.  So far this year's poinsettias look really good. 
Facing west.  As you can see one bench top is up.  I am renovating the hot water heat headers.

one of the advantages of owning greenhouses and being a florist is that I can  grow my own wedding  flower centerpieces.   

More wedding flowers.  The wedding is an outdoor wedding scheduled for 8 Oct.
