Grammar explanation
A verb can be followed by another verb. The second one usually needs to change into the -ing form or the to + infinitive form. Which form you need depends on what the first verb is.
Verbs followed by the -ing form
When enjoy, admit and mind are followed by another verb, it must be in the -ing form.
I enjoy travelling.
He admitted stealing the necklace.
I don't mind waiting if you're busy.
Other verbs in this group include avoid, can't help, consider, dislike, feel like, finish, give up, miss, practise and suggest.
Like and love can be followed by the -ing form and the to + infinitive form. They are both correct.
Verbs followed by to + infinitive form
When want, learn and offer are followed by another verb, it must be in the to + infinitive form.

Hello tikah,
I'm afraid there's nothing in the verb itself which will tell you what form follows it. You simply need to memorise which verbs are followed by verb-ing, which by to+verb and which by the base form of the verb. Some verbs can be followed by more than one form, with changes in the meaning resulting.

Hello Sophea
Thanks for the suggestion. We plan to add more basic grammar pages in the future, but are busy with other projects at the moment.
In the meantime, I'd suggest you look at the Beginner grammar section of LearnEnglish Teens for more topics.

You can find more verbs like these on this and this page here on LearnEnglish, but any good dictionary will show this kind of information (follow the link to see an example).

Hello redream
I'd need to see the phrases in context to say anything for sure, but in general, I understand 'heat source' to be more general than 'heating source'. 'heating' refers to a system used to keep a space warm, whereas 'heat' is more general. Instead of referring to a home or office, for example, it could refer to an industrial process or many other situations.
Hope this helps.
All the best
