First thing to check is thermostat, if your engine takes long time to warm up could be it is stuck open and engine over cools and heater will give only little warmth.
Next a flush of heater matrix, old sludge may be restricting flow.
Another issue can be that even if heater gets hot the seals relating to the heater box may be gone and the warmth is lost before it gets to cab.

The thing with the td5 heater core is that, while it's a bit bigger, it doesn't really fit it the heater box, it's too big.
When you have warmed the engine up go and feel the heater box, it does a very good job of heating the engine bay. For it to be efficient the core would need to fit completely in the heater box and then for that to be insulated. That is a good test to see if the heater is actually generating heat, also it will show the importance of the seal between it and the bulkhead.
