Pond heating

Updating a system on a 6,000 gallon pond - page 2.
The weather was fine on the morning of the second day, but showers were forcast for later. This was fine because once the original boiler was removed and the new assembly was transferred from the garage then the existing cover would keep the installation dry.
 
System assembled outsideSYSTEM ASSEMBLY.

The original boiler was disconnected and removed.
The new system that was assembled in the garage the previous day was now moved outside and reassembled in the new position as can be seen in this photo.
The same wooden blocks were used to ensure it was in the correct position, and then the holes were drilled to take the four rawlplug bolts which hold the heat exchanger in place. The munsen clips have also been fitted to the wall to support the pipes for the air vents, and these can be seen at the top of the photo.

TIP. The heat exchangers are quite large and will contain quite a fair amount of water. This must be borne in mind when fitting them to the wall, and so rawl bolts are much better than plugs and screws.
 
Old pipeworkADAPTING OLD PVC PIPEWORK.

At the bottom of this photo we can see the high pressure pipework which was in place for the original boiler.
The same pipework will be used, but as the bends are in the wrong place then the straight lengths of the existing pipes are already cut and they will be joined by straight connectors to the new pipework.

On the extreme left of the photo can be seen the gas inlet for the boiler. The existing supply was in this position, and it was only a case of altering the position of the valve and connecting the new 15mm pipework.
 
New pipeworkFITTING NEW PVC PIPEWORK.

This photo shows the new pipework after it has been glued into position.
It will be noted that the two old bends have been used again, and these are in a different position and have been positioned with new short lengths of pipe and straight sockets.
It will also be noted that 45 degree elbows have been used instead of 90 degree elbows so that there will be less restriction to the flow.

90 degree elbows have been used on the heat exchanger, and it will also be seen that unions have been used in the pipework close to the heat exchanger so that it can be removed later if required without disturbing the rest of the pipework.
It is difficult to see because of the angle this photo was taken, but the pvc pipes are in line with one another and are parallel to the slabs on the floor.

 

Close-up of new pipeworkNEW PVC PIPEWORK.

This is a close-up view of the new pipework. All the pipework was cut and assembled together without glue until the pipework was in line and exactly as required. All the joints were then marked with black felt pen so that they can be correctly aligned when they are glued together.

WARNING. Care must be taken when building a system such as this unless you are conversant with this type of work. If you are not qualified to do the wiring yourself then consult an electrician. In Great Britain it is a criminal offence to connect the gas system yourself, and this must be done by a CORGI registered fitter. If you are doing this in any other country then do get expert advice and make sure that all the installation and work confirms to local regulations.
